The packing material that we receive from our suppliers, we try to re-use as much as possible.

To save the environment as much as possible, we try to re-use boxes, so it is possible that you will receive a product from us in a box from one of our suppliers. We only re-use boxes if they still meet our strength standards.”

For shipping to Belgium we charge € 10 per shipment.
For orders above € 150, we deliver free of charge to Belgium, Netherlands and Germany.”

It’s great that you are asking yourself (and our FAQ) this question, as there are many online shops that are not trustworthy.
For that reason, we have a partnership with Kiyoh, a very reputable review platform. Here you can read more than 750 reviews of what kind of webshop we are and what kind of service we provide.
It is not for nothing that we score 8.4 on Kiyoh.

We are in business for almost 15 years and supply several large companies in the Netherlands and Belgium.
Our information can be checked at the Chamber of Commerce -> 63967588.

Shop4power handles its shipments with UPS and sometimes PostNL. This ensures that you receive a reliable delivery within 1 to 2 working days. If you want to make sure that your order is shipped on the same day, please complete your order before 16.00 and do not choose “bank transfer” as a payment method, as this causes a 1-2 day delay in payment. In principle, the track & trace information will be provided to you as soon as possible so that you are constantly aware of the status of your order.

For heavier battery packs, we use a regular transport company, as DHL and PostNL are not able to deliver the order undamaged in these cases. Unfortunately, this transport company does not have track & trace information. For each shipment, you will pay € 6.75 as a contribution to the shipping costs, for shipping to Belgium this contribution to the shipping costs is € 10. Orders from € 150 are shipped free of charge to you in the Netherlands and Belgium.

For all battery set orders, the boxes are extra sealed with special tear-resistant tape. This ensures that the boxes do not tear during shipping. As we ship these batteries with UPS or our own carrier, we are ensured that the boxes are handled well. If a box falls during transport, the extra tape ensures that you still receive your product. The scooter batteries and heavy sets of UPS batteries are shipped with a regular carrier. The carrier leaves a note in your mailbox if you are not home.

Your products are packaged in sturdy boxes with environmentally friendly filling material so that even if the products are put through a hard time during shipping, you still receive an undamaged and well-functioning product. You may also come across packaging that our suppliers have sent to us. We try to reuse as many shipping products as possible to be as environmentally friendly an organization as possible. If your delivery arrives in a (heavily) damaged box, take a photo of the box and make a note with the driver. This way we can claim damages with the carrier later on. If you accept your package without any comments, it is almost impossible for us to claim damages later on with the carrier and/or to compensate for this.

If you want to know what we do to minimize the impact on the environment, you can always call us or send an email to info@shop4power.nl, we would be happy to tell you more about it. If your delivery does not arrive within two working days, please contact us so that we can take action. When you pay with a Credit Card, this may cause a delay of up to 1 day. The credit card company must authorize the invoice before we can process the payment.

eScooter Scootmobiel batteries

To replace the batteries, here are a few handy tips!

We assume that replacing the battery of your eScooter is necessary, if you are not sure you can find some tips in the FAQ “Do I need new batteries for my eScooter?”

We assume that you have purchased the correct battery, if you are not sure or have not yet purchased the battery, you can find some tips in the FAQ “How do I determine the correct battery for my eScooter”

You now have the correct battery. There are the following two possibilities:
1. The complete battery set is in a cassette
2. The batteries are built into your scooter without a cassette.

1. The complete battery set is in a cassette
Try to take precautions if possible: Put on work gloves and put on safety glasses.
Disconnect the cassette from the scooter.
Carefully unscrew the cassette, normally the cassette consists of two parts, the part where the screw heads are located is usually a “lid”.
If you have the batteries exposed, I recommend taking photos of the wiring with your smartphone or digital camera, this way you can easily find out how the wiring ran. If you see a fuse anywhere, check it. If you do not have a multimeter, you can do this with a simple battery (AA or AAA) and a bicycle light. (of course disconnected from the 4 blocks)!!
Remove the wiring from the terminals. Meanwhile, check if all connections are still clean.
Remove the old batteries and place the new ones in the same way as the old batteries.
Close the cassette again and connect the charger, or place the cassette in the scooter and connect the charger. The batteries are already approx. 70% charged when you receive them

2. The batteries are located without a cassette in your scooter.
Try to take precautions if possible: Put on work gloves and put on safety glasses.
An eScooter where the batteries are built-in without a cassette always has a DC switch to disconnect the batteries from the motor. Open this switch. If you can’t find the switch, make sure that you don’t turn on the scooter!
Before removing the batteries from the scooter, I recommend taking pictures of the wiring with your smartphone or digital camera, this way you can easily find out how the wiring ran. If you see a fuse anywhere, check it. If you do not have a multimeter, you can do this with a simple battery (AA or AAA) and a bicycle light. (Of course, disconnected from the blocks)!!
Remove the wiring from the terminals. Meanwhile, check if all connections are still clean.
Remove the old batteries and place the new ones in the same way as the old batteries.
Make sure that all cables run in exactly the same way and don’t get jammed or damaged by friction. Attach them again in the same way and connect the charger. The batteries are already 70% charged when you receive them, let them charge overnight and they are ready for use.

Unfortunately we do not have e-scooter usermanuals.

The main reason for this is that e-Scooters are imported into the Netherlands through many different channels. Normally without batteries. They are build in, in the Netherlands
Every dealer had his own preference for batteries and way of installation, so it’s impossible for us to say with certainty what the battery configuration of your eScooter is.

However, we can help you with the installation. If you send us photos, we can indicate how the batteries should be installed based on that. It’s also possible for us to replace the scooter batteries. We can give you a cost estimate based on photos showing how the batteries are placed.
Replacing batteries in a battery cassette is also something we can do for you if desired.

In principle, you can replace the batteries yourself, as long as you are careful it’s not a problem at all.

Determining the right battery set for your eScooter or other electric device is not difficult. Here are some tips:

1. Determine the number of batteries It is important to know how many blocks are in your electric device. Sometimes this is very difficult to see, you can measure, if you measure around 48 Volt then there will be 4 blocks, if it is more around 60 Volt then there will be 5 blocks If you cannot measure, then you could also look at the DC/DC regulator (usually a metal box of 15 x 6 x 4 cm etc.) on this box, it also often mentions a voltage. Ultimately, your blocks will have to be removed from the scooter for replacement!

2. Determine the capacity of the batteries. Usually the capacity is mentioned on the blocks. If the capacity is not on the blocks, you can measure the size of the blocks and give this measurement to us at info@shop4power.nl, we can then tell you which capacity battery it is.

3. Check the size of your battery. Although it is good to use approximately the same capacity battery, the size is more important. Check if the dimensions of your current blocks match the dimensions of the new set on our website. On the products, this information is available under the “Technical Information” tab.

The data, especially the capacity, does not always match. When we talk about a 33 Ah block, there may be 35 Ah on your current block. These types of differences are not a problem. It mainly has to do with the way of measuring and which measurement values you use.
The most important thing is that the dimensions match and the number of blocks.

To ensure that you can enjoy your batteries for as long as possible, we have put together a number of tips for you.
To make it clearer, we have divided the tips into two types of users.

– Intensive user (long distances, daily use)
After a long ride, charge immediately

– Regular user (short distances, daily use)
Do not charge daily, at least once a week

For short distances, charge the batteries only when the battery indicator shows 50% or at least once a week!
Do not interrupt charging and only disconnect the battery charger when the green LED is on.

When should you replace the batteries of your eScooter, Golftrolley or other electric device?

Often you will notice that the range of your eScooter becomes less. This is the best indicator of a battery set that is aging. As long as it is a decrease that you can live with, no problem. If the decrease is no longer acceptable, then you will have to replace the set.

If you still have an empty battery after charging overnight, do the following:
– Take a DC-voltmeter/multimeter. Measure at the contacts of the batteries on the connection to the charger. That voltage will be around 12-13 volts, if you measure nothing, a fuse may be defective. Remember this measured voltage and connect the charger to your battery. Let the charger charge for one minute and measure the voltage again on the connections. If the voltage has slightly increased, your charger is still working. Then you will have to replace the set.

When the voltage on the connections is 0 Volt, you will have to look for the fuse and test it. If it’s defective, replace it and charge and measure again. If the problem is solved, enjoy it. If the voltage is still 0 Volt, then a block is broken and you will have to replace the set.

“If your current scooter batteries are GEL batteries, then your current charger is also a GEL battery charger. It is best to also buy GEL batteries in that case.

A GEL battery has a lower maximum charging voltage than regular Lead batteries. If you replace GEL batteries with regular cyclic Lead batteries and charge them with a GEL battery charger, the batteries will never fully charge Meaning the range will be lower and the batteries will more quickly become defective.

There are two options:
1. Buy GEL batteries again (available in the online store
2. Purchase regular cyclic-Lead batteries in combination with a regular cyclic Lead battery charger, available in the online store.

Batteries cannot be returned because we cannot check if they have been used or not.

A Gel battery is a more robust version of the Lead battery because the acid in the battery is thicker. The GEL battery is therefore better able to withstand deep discharge. A scooter has a controller that prevents a battery from being deeply discharged. Therefore, it is not really necessary to use a GEL battery. Our importer advises to use “regular” Lead-acid batteries. Please note!! If you replace GEL batteries, then you have a GEL charger, you must purchase GEL batteries, or also replace the charger.

The difference between the two Li-Ion versions T1 and T2 lies only in the dimension. Of course, with equal Ah.”

A set of batteries, bought at the same time, will also age at the same time With aging, the internal resistance of batteries increases.

In an aging set, the following can happen:

– The capacity decreases. Often, the voltage across the blocks is still the same when measured and people decide to replace the entire set.

– Blocks become thicker – A 12V Lead block consists of 6 cells, so 6 x 2V = 12 Volts. At some point, lead plates may come into contact with each other within a block. This means that a cell is lost.
This means that there is less voltage across this block because there are now 23 cells instead of 24 cells. This means that the blocks with 6 cells have 12.5 Volts instead of 12 volts.
(Values are different at charging voltages, this is for the calculation example).
So if you measure the blocks, you will measure 3 blocks that have actually received too high a voltage in recent times and therefore seem to be functioning perfectly.

The choice is clear! Add 1 new block and go!

Now we have 3 “old” blocks and 1 new block with a lower resistance.
The same current flows through all 4 blocks (series chain), Ohm’s law U = I x R means that the voltage across the old blocks is higher than across the new block.
The old blocks are now really having problems because they are continuously overcharged and are therefore going to be damaged. Often, plates come into contact with each other which means that a block receives less voltage and the rest of the
blocks carry even more voltage. They then become round and really damaged.
Then you will have to replace 3 old blocks after all.

If you’re very lucky, the “new” block has not been damaged by the events. Then you can connect the three new blocks in series with the relatively new block.

If you’re unlucky, this new block has still been hit and you will need four new blocks.
If you’re very unlucky, you think you’re done with three new blocks, but the poorer new block still damages the three newer blocks and you have to buy another 4 new blocks.

Is that number with the S at the end important or not? Yes, it is very important. The charger and the battery/battery must have the same S number to function properly. A Lithium battery is actually composed of all small coupled cells to reach the required capacity and voltage. The cells can be coupled from + to -, in series and rows of serial cells can then be coupled from + to + and from – to -. Series increases the voltage and if you have the right voltage, you can connect multiple in parallel to achieve enough capacity. The 13S and 14S are versions for the 48V scooters and the 16S and 17S for the 60V applications. It is important to choose the right charger based on the number of cells in series because otherwise the battery will be overcharged or not fully charged. In the technical specifications of each charger, it states how many cells are connected in series.

Almost all electric scooters have 4 or 5 batteries/accus. Many customers are misled because they only see 3 batteries when they open the scooter. However, there is usually one more battery hidden under the others. If you want to check how many batteries you have without taking the whole scooter apart, you can look at the charger. If the charger says 48V or 48 VDC or 48Volt, then there are 4 blocks in the scooter. If it says 36V, then there are 3 blocks. The voltage of the motor is also often printed on the metallic box that you can see when you remove the seat. The voltage of the motor is also often printed on the metallic box that you can see when you remove the seat. If you still have doubts or can’t find it, feel free to contact us: 085-4019230 or info@shop4power.nl”

Increasing the range is related to the number of Ah, ampere-hours. This is the capacity of the battery set. If you have lead batteries, you can choose for batteries with a larger capacity, but you have to pay attention to the size because higher capacity means a larger battery. If the battery with the larger capacity doesn’t fit, then you have another option: switch to Lithium, Lithium has a much higher energy density so you can fit much more Ah in the same space than with lead batteries. Keep in mind that when you switch to Lithium, you also need a different charger. It is even so that a 30Ah Lithium battery drives much further than a 30Ah lead battery. An electric scooter can function without problems with lead or Lithium.

Shop4power supplies batteries from different manufacturers. For the cyclic batteries, we often supply batteries from the same supplier. From this supplier, Intercel, we have set up a table with the dimensions per type of block in mm.

The difference between the Normal cyclic battery and the Extreme version is the number of discharges. The Extreme is able to deliver even more discharges than the normal Cyclic, which is specially made for these applications.

Capacity    Type of block    Length       Width       Height    
12Ah   151 98 98
18Ah   181 76 167
20Ah Extreme 181 76 166
24Ah   166 175 125
26Ah Extreme 175 166 125
33Ah   197 131 170
33Ah Extreme 195 129 179
38Ah S*   197 131 168
38Ah   198 166 171
40Ah Extreme 197 165 171
50Ah   198 166 171

The 38Ah S* has a capacity of 38Ah at a 20h discharge!! The capacity of the rest of the blocks os based on 10h.

Power over Ethernet

The network cable must not be longer than 100 meters after a PoE injector. After this, the voltage loss over the cable is so high that proper operation of the connected PoE equipment can no longer be guaranteed.

WHY?
A copper cable (or other material) always has a resistance – Ohm. When current flows through a cable I, a portion of the total voltage Ut will be lost through the cable resistance R.
This is because the voltage Uv is created by I x R.
The longer the cable, the greater the resistance.

To have an acceptable voltage at the end of the cable, it should not be longer than 100 meters.

If one still wants to use a longer cable than 100 meters, one should use a PoE Extender, such as the PoE-E101 or the PoE-E201. With the help of a PoE extender, the maximum distance can be extended several times. These PoE extenders can be ordered on our webshop.

Your PoE device must comply with the IEEE802.3a standard, such as the IEEE802.3af or at standard. You can find this in the specifications of your device. Sometimes a brand uses its own PoE standard, then it is not entirely certain that we can power it. Our Planet products meet internationally established standards.

You should pay attention to a few things:
– The network speed
– The required power
– Injector, splitter or extender
– Normal use or industrial application

The network speed:
We have 10/100Mbps but also 10/100/1000Mbps injectors and splitters in our webshop.

The required power:
We have normal PoE systems but also High Power PoE and Ultra Power PoE, which you can use for example for Dome cameras with pan – zoom – tilt functions.

Injector, splitter, or extender:
In this, people often make the wrong choice because a splitter is cheaper than an injector. At the beginning of the network cable, an injector is placed, after which the network cable goes to the user. If the user is a PoE user, the cable can be connected directly, if not, the splitter can be used to split the Data-PoE signal into a data and power connection. If you want to cover distances greater than 100 meters with a Data-PoE signal, you need an Extender after 100 meters, PoE-E101 or PoE-E201.

Normal use or industrial use:
At home or at the office, you can use standard Planet solutions, however, if you want to place equipment outside or in factory halls or other humid, cold, or hot locations, you should choose an industrial Planet POE solution.

When applying Power over Ethernet, there are a few things to consider:

– First, check if your equipment is suitable for POE. Then, make sure that the PoE device complies with the IEEE 802.3af/at standard.

If the equipment is suitable, you have the outgoing side covered. Then, you need to add POE on the network cable on the power side. This can be done with a PoE Switch (802.3af or at, depending on the standard that the user meets) or by using an injector. If you already have a switch or modem/router that does not inject POE, it is convenient to use an injector (single port or multiple ports). Make sure that if you have 802.3at users, the injector/switch is also 802.3at. If you only have 802.3af users, an 802.3af switch/injector is sufficient, but you may also use an 802.3at switch/injector, perhaps with an eye on the future.

– The length of the cable is also important. The standard network cable must not be longer than 100 meters. If the cable is longer, you can use a PoE extender. Again, pay attention to the 802.3af or at.

The Hikvision / or another camera can normally be powered in two different ways.

– 12V 1A or
– PoE (IEEE802.3af/at)

The IEEE802.3af standard indicates that you can use a fast ethernet solution.
It doesn’t necessarily have to be a gigabit POE solution.

The misconception is that the PoE power is 12 volts. That’s not the case. The PoE voltage is much higher, around 48 Volts.

For your application, it doesn’t matter. There are roughly three ways to do this:

– If the data cables come from one central point and need to be switched,
– use a POE Switch
If the data cables come from one central point and don’t need to be switched, use a PoE injector hub
– If the data cables come from different points,
use PoE injectors.

A Switch is not necessary as you already mentioned.

If you are going from one point to multiple cameras and you already have a switch, you can use a PoE injector hub. With such a hub, you connect each cable that would normally go to the camera first to the HUB, and from there you continue to the camera, but now with PoE injected on the cable. Depending on the number of cables, you can choose a 4, 12 or 24 port solution. If each cable goes from a different location to the different cameras, you should choose injectors. In your case, the PoE-151 could be a good choice. In your case it could be a PoE-151.

If you think that you have chosen a completely covering standard with the IEE802.3af standard, you are almost right.

The standard works fine, the only thing you still have to pay attention to is the pin assignment. Within the 3af standard, there are two versions of the use of the wires, namely MODE A (Endspan) and MODE B (Midspan).

With Mode A (Endspan), both the data and the power supply are sent over wires 1, 2, 3 and 6. The other two pairs of wires are not used in 10/100TX.

With Mode B (Midspan), the data is still sent over wires 1, 2, 3 and 6, but now the power supply is sent over the two unused wire pairs 4, 5, 7 and 8.

At shop4power, the “Technical Information” TAB always clearly indicates whether it is a Midspan or an Endspan in the product, and also clearly indicates which pins are used for the PoE power supply. If you then compare this information with your product to be supplied, it should go well.

UPS Batteries

We use sturdy boxes for shipping and we always make sure that the batteries are separated from each other by cardboard so that they do not damage each other and also so that the contacts do not make a connection.

To ensure that the batteries do not break the box due to their heavy weight, we use special cross-reinforced PP-tape with fiberglass wire. It is almost impossible to tear this tape.

There are a huge number of different UPS systems on the market, and some types even come with different battery sets. Usually, the manual will indicate which battery replacement you need.

If this is not the case, you can find the correct blocks through the supplier.

For APC UPS systems, there is always a model number that you can use to find the correct battery. In the image below, you can see an example of an APC model number (SMT1500MI1U)

The only solution that always works is to open your UPS and photograph the batteries inside and send them to us with dimensions via email – info@shop4power.nl – we will let you know within 4 hours which battery is suitable for you.
You can also send us an email with the brand and type of UPS for which you are replacing the battery, and we will tell you which battery you need.

We try to continuously adapt our sets to all UPS systems that are available on the market. However, it may be that your UPS does not appear in this list and that you still expect that this is the right battery set for you. The best option at that time is for you to contact us, that can be done via email info@shop4power.nl or by phone: +31 85 – 401 92 30.

We supply complete sets. The different sets are delivered complete, but without cables and fuses.

In the battery text, we indicate the number of blocks in the battery set.
This quantity is also the number of blocks that we deliver for the mentioned price. These are NEW batteries, specially suitable for use in UPS systems from, for example, APC, MGE, BELKIN, CHLORIDE, etc.

Shop4power is a partner of Maas Energy Systems B.V.

MES always keeps batteries in stock for service purposes. For our customers, we need a stock on hand. It is not easy to always keep “fresh” blocks because we do not always need them. By also selling these batteries as RBC sets via shop4power, it is possible to always have “fresh” batteries, not only for the web shop but also for Maas Energy Systems’s customers.

Through this structure, we are less interested in high margins and more in high turnover. We achieve this high turnover most easily by using very sharp prices on the web shop.

How do I find the correct battery replacement for my UPS?
It is virtually impossible for us to place all the discriptions with the sets

With APC, abbreviations are usually used, for example, the Smart UPS is called SU. If you have an APC Smartups 750, you can search for su750.

Of course, the RBC number is often also on the back of the UPS or in the manual.
Many sets are the same, so that makes it confusing for you sometimes.

You can also email us the dimensions of the current batteries, then we will know exactly which set you need.

If you really don’t know, you can send us an email at info@shop4power.nl and we will always answer within an hour (7 days a week from 08:00 – 22:00). Calling is also always possible at +31 85 401 92 30.

WE HAVE ALL SETS IN STOCK!!

We deliver the battery sets without fastening materials, many suppliers charge huge amounts for the sets, this is not necessary, you can simply reuse the materials with our blocks and save a lot.

By default, we deliver the same quality batteries as the ones already in your system. All single-phase (230Volt) UPS systems are delivered with batteries of the “commercial rating” type. This means that the blocks normally last for 3-5 years. If you think that your blocks are going much longer than that, the chances are very high that your blocks have been defective for a longer period but were needed.. A standard UPS only notices that a battery is defective when it is used, for example during a power failure.

For that reason, it is also wise to have your UPS perform a battery check every 3 months. Some UPS systems can have this set up software, others can be tested on the front of the unit.

We can provide you with the right batteries for all UPS systems, for all single-phase (230Volt) UPS systems we can even deliver from stock. Our standard stock makes it possible to provide about 100 UPS systems with batteries per day.

If you prefer batteries with a longer lifespan, this is also possible, you only have to send us an email: info@shop4power.nl

Most alarm systems use a single 12 Volt 7Ah block. This block is exactly the same as the blocks in a UPS. For this application, you can use the S4P-RBC2

UPS Systems

It always remains difficult to determine the total power of equipment.

Ultimately, measurement is still the best way. Shop4power has the possibility to carry out a power measurement on site. If you do not want a measurement, you can also look at the type plates of the equipment to see what the power consumed per device is and add them together. However, you should keep in mind that the power listed on computers and similar devices is usually in watts and not in kVA. The easiest thing to do is to note everything down and contact us. We can then indicate what your power consumption is approximately.

The problem with working with powers and/or currents listed on the type plates of equipment is that these data are usually based on the power supply that is in the system. The fact that a power supply, for example, can deliver 450 watts of power does not mean that the computer in which it is built actually consumes this power. The actual power consumption is often much lower when reading the type plates than when measuring the power consumed. Of course, you can always send us a list of equipment to be secured, and we can then determine the total power consumed based on this list. Keep in mind that when choosing the UPS system, you also have to take into account growth and reserve capacity in case of, for example, start-up phenomena (a device that normally consumes, for example, 500 watts could consume 4 times as much when turned on).

The term U.P.S. stands for “Uninterruptible Power Supply”. This term is a very broad concept. It encompasses all UPS versions that are available.

Other terms for UPS are, for example:
– No Break
– Emergency Power unit
– Power supply
– etc.

There are different UPS systems:
– On Line – Double Conversion – True online – VFI UPS
– Line Interactive
– Digital On-Line
– Off Line
– Static UPS
– Rotary UPS
– etc.

The autonomy of a UPS, also known as runtime or backup time, is the amount of time that the UPS can power the load without external power. In essence, it refers to the size/capacity of the battery. The choice of autonomy depends on a few things.

Firstly, you must decide what you expect from the UPS.

– If the UPS is used to bridge the time until the emergency power generator is started
then the UPS only needs a few minutes of autonomy.

– If the UPS needs to shut down the IT systems immediately upon power failure,
then the autonomy should be at least as large as the time needed for the shutdown.

– If you want to investigate the cause of the power failure, such as a tripped circuit breaker,
you need to determine how much time such an investigation takes, including the time required for the IT systems to shut down.

– If you want to stay online for as long as possible, for example for telephone companies, they need to be availble to their customer up to the last moment!

then the biggest problems arise. With a large battery, you need to consider multiple things
– such as the size and weight of the battery set
– whether it is financially more interesting to buy an emergency power generator in combination with a UPS and small battery,
– and whether the battery is too large for the UPS or the charger of the UPS and what this means for the recharge time.

Many of the UPS systems from Shop4power have the ability to be expanded in terms of autonomy with additional battery cabinets. These are then connected to the UPS unit. For UPS systems where this is not possible, the autonomy can be increased by choosing a larger UPS. Sometimes this is financially interesting.

A On-line UPS, also known as a double-conversion UPS, is the only “true” No Break system.

With an on-line UPS, the total power consumed by the UPS is converted into a DC voltage by the rectifier. oth the battery and the inverter are connected to this DC voltage. In this configuration, the inverter at the output does not know whether it is being powered by the rectifier or the battery.

During “grid operation”, the rectifier powers the inverter and also keeps the battery on “trickle charge”. If the power goes out, the battery will seamlessly take over the power supply to the load without interruption, the load does not notice the difference between grid or battery power. Since the term “On-line” is not protected and can be used for other types of UPS, one also speaks of a “True On-line UPS”.

The term VFI (Voltage, Frequency Independent) is protected which means that the UPS is independent of voltage and frequency. which means that the UPS is independent of voltage and frequency. It doesn’t need to switch to battery power in case of a variation in voltage or frequency.

A Line-Interactive UPS can handle voltage variations without battery power, but not frequency variations. This UPS is called VI-UPS Voltage independant
an Off-line UPS can handle neither voltage nor frequency variations without battery power. This UPS is called a VFD-UPS Voltage, Frequency dependant.

There are different types of UPS systems
The three most well-known are:

Off-line.
Line-interactive.
On-line (double conversion).

A line-interactive UPS is similar to an off-line UPS, but with the main differences being that it has a better filter and is equipped with a “fader” that can adjust high voltage without switching to battery power. Some line-interactive UPSs also have a “booster” that can increase low voltage without battery power. A Line-intercative UPS normaly has a sinusodial waveform when working on battery.

They are usually used in LAN environments such as CAD workstations and less critical servers.

However, UPS naming is not protected and is often misused.

Off-line
An off-line UPS, also known as a stanby UPS. is typically applied to loads that are not sensitive to very short interruptions. When the power supply from the energy grid is present, the UPS only keeps the (internal) battery charged and passes on the input power to the load. In case of a voltage drop, an off-line UPS switches from normal power to battery power. The UPS contains an inverter that converts the battery’s DC power to an AC power. Usually, this is a single-phase AC power.

When the power supply from the energy grid is present, the UPS only keeps the (internal) battery charged and passes on the input power to the load. In case of a voltage drop, an off-line UPS switches from normal power to battery power. The UPS contains an inverter that converts the battery’s DC power to an AC power. Usually, this is a single-phase AC power. Because the inverter is only “on” during normal operation, it has to switch on when there is a power failure, which results in an interruption of 5 to 10 ms. Such a UPS has a small rectifier at the input that only keeps the battery charged.

Since an off-line UPS only switches between grid power and battery power, the system is set to a certain allowed variation (bandwidth) of voltage and frequency. The system does nothing within this bandwidth, but outside of it, it supplies the load from its battery. Especially advanced computer systems are sensitive to very small variations in voltage and frequency. For these computer systems and other sensitive/valuable systems, an off-line UPS is not suitable. Additionally, an off-line UPS is usually equipped with a simple inverter that is not able to produce a sine-wave AC power on battery. Often, this UPS produces a block voltage or a trapezoid wave. Many devices cannot work with this. It is therefore important to check whether your equipment can work with a trapezoid or block wave.

Een off-line UPS wordt doorgaans uitgevoerd met een zeer eenvoudig filter of zelfs zonder filter. A filter protects your equipment from grid pollution. This protection is hardly present in an off-line UPS.

Because an off-line UPS only uses its rectifier to charge the battery, it is relatively small. This allows for a significant cost and size savings. The same applies for the inverter, it only needs to function during an outage or when the voltage or frequency is out of tollerance. This allows for a smaller and lighter inverter. .Because of these savings in costs and size Off-Line UPS systems are smaller and cheaper than Line-interactive and On-line UPS’s.

An off-line UPS is suitable for less critical workstations and for allowing a home computer to save data safely before shutting down in case of a power failure.

On-line

A On-line UPS, also known as a double-conversion UPS, is the only “true” No Break system. With an on-line UPS, the total power consumed by the UPS is converted into a DC voltage by the rectifier. On this DC voltage / DC Bus the battery and the inverter are connected. In this configuration the inverter does not notice being fed from the utility power or the battery During “grid operation”, the rectifier powers the inverter and also keeps the battery on “trickle charge”. If the power goes out, the battery will seamlessly take over the power supply to the load without interruption, the load does not notice the difference between grid or battery power. Since the term “On-line” is not protected and can be used for other types of UPS, one also speaks of a “True On-line UPS”. It can be stated that a True On-Line UPS is suitable for critical applications such as servers and industrial equipment, where a short interruption is not acceptable. Because a True On-Line UPS uses a rectifier and an inverter that continuously supply the full power of the load, these components are more heavily designed than in an off-line UPS and a line-interactive UPS, so a real on-line no-break system is relatively expensive.

A True On-Line UPS system can be used everywere where the reliability and quality of the feed is important. A True On-Line UPS system delivers the best protection for critical applications!
