A UPS is a very profitable device. As long as it works, the user has no problems with power supply. But the functionality of this device does not end there. The simplest modification of an uninterruptible power supply makes it possible to create on its basis such devices as a converter, power supply and charging.
How to convert an uninterruptible power supply into a 12/220 V voltage converter
A voltage converter (inverter) converts 12-volt direct current into alternating current, simultaneously increasing the voltage to 220 volts. The average cost of such a device is 60-70 US dollars. However, even owners of worn-out uninterruptible power supplies with a battery start function have a very real chance of getting a working converter for virtually nothing. To do this you need to do the following:
Open the UPS case.
Dismantle the battery by removing two wires from the storage terminals - red (to positive) and black (to negative).
Dismantle the speaker - a sound signaling device similar to a centimeter washer.
Solder a fuse to the red wire. Most designers recommend using 5 amp fuses.
Connect the fuse to the “input” contact of the UPS - the socket where the cable connecting the uninterruptible power supply to the socket was inserted.
Connect the black wire to the free contact of the “input” socket.
Take a standard cable for UPS connections to the socket, cut off the plug. Connect the connector to the input socket and determine the wire colors corresponding to the red and black contacts.
Connect the wire from the red contact to the positive of the battery, and from the black to the negative.
Turn on the UPS.

This transformation is allowed only by uninterruptible power supplies with a battery start function. That is, the UPS must initially be able to turn on from, without connecting to an outlet.
If the UPS has a standard outlet, 220 volts can be removed from its contacts. If there is no such outlet, it will be replaced by an extension cord connected to the “output” socket of the uninterruptible power supply. The extension plug is removed, after which the wires are soldered to the contacts of the “output” socket.
The main disadvantages of such converters:
- The recommended operating time of such an inverter is up to 20 minutes, since UPSs are not designed for long work from batteries. However, this drawback can be eliminated by embedding a computer fan operating from 12 V into the UPS case.
- Lack of battery charge controller. The user will have to periodically check the voltage at the drive terminals. To eliminate this drawback, you can embed a regular automotive relay into the design of the converter by soldering the red wire behind the fuse to pin 87. At correct connection such a relay will turn off the power supply when the battery voltage drops below 12 volts.
How to make a power supply from an uninterruptible power supply
In this case, of the entire design of the uninterruptible power supply, only . Therefore, the user who decides to remake the UPS in this way will have to either gut the entire UPS, leaving only the housing and transformer, or remove this part, preparing for it separate building. Then proceed according to the following plan:
Using an ohmmeter, the winding with the highest resistance is determined. Typical colors are black and white. These wires will be the input to the power supply. If the transformer remains in the UPS, then this step can be skipped - the entrance to the homemade power supply in this case will be the “input” socket at the end of the UPS, connecting the device to the socket.
Next, the transformer is supplied AC at 220 volts. After this, the voltage is removed from the remaining contacts, looking for a pair with a potential difference of up to 15 volts. Typical colors are white and yellow. These wires will be the output from the power supply.
The input to the power supply is formed from wires on one side of the core. The output from the block is formed from wires located on the opposite side.
A diode bridge is installed at the output of the power supply.
Consumers are connected to the contacts of the diode bridge.
Transformer
The typical voltage at the output of the transformer is up to 15 V, but it will drop after connecting it to a homemade load power supply. The designer of such a device will have to select the output voltage through experimentation. Therefore, the practice of using a UPS transformer as the basis of a power supply for a computer is far from the best idea.
Converting an uninterruptible power supply for charging
In this case, a minimal transformation similar to that described in the paragraph above is not needed. After all, the uninterruptible power supply has its own battery, which is charged as needed. As a result, to turn the UPS into charger you need to do the following:
Locate the primary and secondary circuit of the transformer. This process is described in the paragraph above.
Supply 220 volts to the primary circuit by inserting a voltage regulator into the circuit - as such, you can use a rheostat for light bulbs, replacing a traditional switch.
The regulator will help calibrate the voltage on the output winding in the range from 0 to 14-15 volts. The place where the regulator is inserted is in front of the primary winding.
Connect a 40-50 ampere diode bridge to the secondary winding of the transformer.
Connect the terminals of the diode bridge to the corresponding poles of the battery.
The battery charge level is monitored by its indicator or voltmeter.

How to choose a UPS for your computer
After the user has learned about the existence of such devices and got to know them better, he may want to purchase a power supply for himself. But in order to buy, you must first carefully weigh the advantages and disadvantages" and decide whether the user really needs this device. After a positive answer, you should understand UPS better so as not to get into an unpleasant situation or waste more money than originally expected.
First we need to understand the terminology. Power factor is defined as the ratio of "real force" to "apparent power", but this is not a technical article, so that's all we're going to say on the subject. But it's the watt figure that's important to today's data centers, so we can accept the mystery.
We need to understand that this thing called power factor is rarely 0, except for incandescent light bulbs, heaters, and toasters. It is usually less than 0 and never greater, so watts are usually less than volt-amps. With better power factors it's even less, which is why we said the error isn't a big deal unless you have a lot of hardware.
The power of the uninterruptible power supply (VA) must be equal to the connected load(BT) and the resulting value is divided by 0.7.
It is very important to note that sellers may confuse VA and W, which may cause a discrepancy in the buyer's calculations and the seller's recommendations. If we assume that the buyer follows the lead of the seller, who made such a common mistake, then he will have to be content with an uninterruptible power supply, the power of which will be significantly less than expected by about 1.4 times, which can subsequently cause problems, not to mention a spoiled mood.
Utilities regularly summarize the reasons for any power outages in their newsletter or regular reports. Causes range from everything in the list above to animals getting into transformers and other components. Whether the power outage occurs for a few seconds or several days, work must continue. And they must do this continuously and consistently.
Reasons vary, but disruptions raise concerns about how projects will be completed on time and on budget. Every business and household needs lights, heat, equipment and other essentials to thrive. Without power, trauma, loss, damage and reduced income become unnecessary.
Conclusions
Uninterruptible power supplies are devices that can help users in their work on personal computers. In addition to the power maintenance function, some uninterruptible power supply models carry out control function monitoring voltage and preventing breakdowns. It can be stated that uninterruptible power supplies can prolong the operation of a personal computer and protect it from the adverse effects of power supply problems.
Now imagine another scenario where there is a power outage. In the event of a long-term outage, it allows plenty of time to convert to an alternative power source. Imagine that your building is a building that continues to hum despite the circumstances, and the people inside it experience calm rather than chaos.
What are uninterruptible power systems?
And with a complete system, you can remove "power failure" from your list of problems. Technology continues to improve as the importance of conserving power for essential systems and operations becomes more and more important. Many people don't realize how much the data-driven world has changed overall energy needs, as the Internet and big data in general continue to drive demand for cleaner, more reliable electricity. Energy surges, spikes or dips cause fluctuations and disturbances that can adversely affect your equipment and your data, so systems provide a clean, consistent and continuous flow of power that protects against these effects.
No one is immune from the unpleasant consequences of various power failures. This can happen to any user of personal computers. But problems can be eliminated by having an uninterruptible power supply, which will perform a protection function and get rid of troubles.
Choosing an uninterruptible power supply is not so difficult, but this process cannot be called definitely easy. The fact is that all the characteristics of uninterruptible power supplies are not so easy to fit in your head, and not everyone can figure it out. But in principle, if you remember the main important functions of uninterruptible power supplies, you will be able to choose a device that is suitable specifically for a specific personal computer.
Generally speaking, an uninterruptible power supply system can be anything from a small black box that sits somewhere next to your desk and protects your personal computer from megaton, megawatt models capable of managing big business. Power Outage Protection Provide sufficient power during short interruptions and “drive time” to convert to backup power. Include a backup power source for long-term outages such as generators. Review the quality of power as it enters the building, office, and equipment. . You'll typically find battery-powered systems in smaller operations such as home computer or office, as well as flywheel configuration in large systems used to power large facilities.
Purchasing an uninterruptible power supply for your personal computer will allow the user to avoid problems that are most often associated with failures in power supply networks. If a problem occurs, the uninterruptible power supply will be able to switch to battery power, which will prolong the operation of the computer. This will allow the user avoid probable problems with data corruption or loss.
There are enough manufacturers of uninterruptible power supplies for computers, but you shouldn’t rack your brains and choose a device from a specific manufacturer from the entire expanse of the presented assortment. This does not justify the effort and nerve expended. There is no need to conduct a deep comparative analysis, since essentially all models of uninterruptible power supply systems that have similar characteristics cost the same and work approximately the same.
UPS are indispensable assistants to users who perform a huge amount of work and whose activities are inextricably linked with the computer. You can rely on the illusory quality of power supply networks and their uninterrupted operation, but it is better to be practical and once again play it safe.
Unfortunately, interruptions sometimes occur in our electrical networks, and in such situations it is necessary to protect expensive equipment from overloads. In addition, in such cases it is important to save information on the computer from irretrievable loss. For this purpose, there are uninterruptible power supplies, abbreviated as UPS. Today we will talk about how to choose a good UPS for a computer, and what is important about this device. There is a huge amount of similar equipment on the market, and if you decide to read this article, it means you can’t decide on the final option. Good power supplies for a computer today can be produced using a variety of technologies. Depending on the purpose for which you use the computer, you need to choose this equipment.
Types
First, it’s worth talking about the main types of uninterruptible power supplies for a computer, of which there are three options on the market.
Reserve
Backup UPSs are the most primitive in terms of design. They differ in that they respond to a power supply delay of 10 ms. At this point, switching to the battery occurs. Such budget computer power supplies are suitable for private home use only if you do not have any problems with power outages. There is no voltage stabilizer, which means that during any interruption the device will switch to the battery, which has a detrimental effect on its service life.
Linear interactive
Line-interactive computer power supplies solve this problem. In the event of voltage surges in the network, they are automatically adjusted to the existing current level. This significantly increases the service life of the device. In terms of price-quality ratio, power supplies for a computer of this type are considered the best.
Online
The best, but most expensive, are online UPS. they react to a voltage drop in the network instantly. The operating principle of this type is the double conversion of incoming electricity. First, the rectifier converts AC voltage to DC voltage. Then the inverter converts it back into AC. But unlike reserve and and interactive computer and other devices constantly receive energy from the online, and voltage-equalized pure sine wave electricity. This device constantly responds to changes in current and transmits this information to the computer.
Basic parameters
Here we will look at the main criteria for devices that will help you make your choice. It will also be possible to understand exactly what parameters affect the cost of equipment.
Power
Power is considered one of the main characteristics of any UPS for a computer. If the total power of the computer exceeds the power of an inexpensive computer device, this may lead to the latter failing or causing constant reboots. Be sure to pay attention to this parameter before purchasing. You need to know how much power your personal computer and all the peripheral devices connected to it consume. To determine this indicator for uninterruptible power supplies, it is worth multiplying the available total value by 1.4. It is precisely this power reserve that is needed for this device.
Time battery life
This parameter is approximately the same for most budget UPSs for computers. Battery life is approximately 5-8 minutes. This is often enough to save all applications and shut down operating system in the correct mode. For those who use their PC resources to the maximum, this may not be enough. Fortunately, some manufacturers offer models whose battery life increases to 15-20 minutes. Of course, you can increase the battery capacity yourself and make it better. To achieve this, manufacturers release additional batteries onto the market. By using them, the required timing characteristics can be achieved.
Software
Many of today's best UPSs for computers come with special programs that allow you to save statistics files on the operation of the device. If a person is not at home, the equipment will independently save all working information on the hard drive. This is quite useful option, the presence of which you need to pay attention to when purchasing.
Number of connectors
Inexpensive computer UPSs often come with just a computer connector. In fact, there may be a wide variety of peripheral devices nearby. You need to calculate how many such devices you have at home, and based on this, draw conclusions regarding the purchase of this or that equipment. There should also be an outlet with protection against power surges. Don't forget about protecting the telephone line. If this is not done, then the modem connected to it may soon fail during a power outage.
Noise level
This is also worth paying attention to before purchasing a power supply. Some inexpensive computer UPSs are quite loud, which can cause various problems; for example, a person may experience headaches. Avoid installing the power supply directly next to your bed. It’s even better to separate it from your sleeping place with a partition.
Display and controls
Today's best UPSs for a computer are capable of not only supplying sound signals in case of switching operating modes, but also provide information using LEDs. This is very convenient if it is possible to visually monitor the state of the block. Some models are capable of informing the user when the battery needs to be replaced. Relatively recently, equipment equipped with liquid crystal displays has appeared on the market. Up to 20 different block states can be displayed here. In addition, some models are supplemented with controls. They allow you to configure the power supply for a specific network operating mode.
Possibility of battery replacement
Today on the market you can find uninterruptible power supplies for computers, which involve replacing the battery during operation. The average battery life is approximately 5 years. During this time, it completely exhausts its resources. There are models that require replacing the battery after its service life has expired. Pay attention to them before purchasing, because it is better to buy a battery than a new UPS, and such devices will save your money in the future.
Manufacturers
Today on the market you can find various both expensive and inexpensive UPSs for computers. There are a lot of manufacturers of such equipment. The best companies are considered to be APC, FSP, Ippon.

Why recycle old UPSs?
Every person should know that an old battery is a hazardous waste that can harm the environment and human health. The substances that make up the UPS (uninterruptible power supply) are extremely dangerous and toxic. Such a device, once in a landfill, releases toxic components into the soil and water, poisoning everything around it. Lead is especially dangerous. This metal slows down plant growth and also causes serious illness in animals and humans.
Everyone can use a UPS, but few know how to recycle it
This is why it is important to dispose of the device correctly. Simply throwing the battery in a landfill, much less storing it at home or in the garage, will not be enough. It is necessary to hand over the battery to a collection point so that experienced employees can dispose of it in accordance with all safety rules.
Benefits of UPS Recycling
By handing over your old power supply to a collection point, you can:
- Safely get rid of unnecessary things;
- Opportunity to protect the environment;
- Provide industrial enterprises with material (all delivered UPSs ultimately end up in processing plants, where lead and plastic are extracted from them and new devices are manufactured);
- Receive a decent reward for each battery sent for recycling.
What is a UPS
General information
A UPS (UPS) is an uninterruptible power supply that can supply power to other devices if there is no current in the main power supply.
They are often used in offices, where unplanned shutdown of computers is unacceptable due to the risk of losing important data, as well as in everyday life. In addition, uninterruptible power supplies are also used in other systems, for example, in server networks. Overall, the UPS creates necessary conditions in order to maintain the functionality of devices in the event of power outages, safely save data and turn off equipment.
The UPS has a service life of 3-5 years, after which the device must be disposed of at the nearest collection point.
After seven years of use, any UPS must be disposed of
Design and types of uninterruptible power supplies
UPS typically contains metals such as nickel, iron, antimony, cadmium, copper and lead. The main element of the UPS is battery. It is she who accumulates the necessary energy.
UPS batteries are divided into 3 main groups:
- Lead;
- Nickel-cadmium (alkaline). Mainly used in trains, subways, carriages, elevators;
- Gel. They are used in the construction of residential autonomous power systems.
About reception points, who they are, why they need it
Where to take the old UPS
Today you have several opportunities to hand over your uninterruptible power supply. First, go to an auto parts store. Some car dealerships are engaged in purchasing failed batteries, including UPS. However, check in advance whether such a device is accepted.
Secondly, you can take the battery to a specialized collection point for batteries or scrap metal. At the moment, there are similar organizations in every city. This option is much more profitable in terms of profit, since in acceptance prices for old UPSs are usually higher than in car dealerships.
How to choose a collection point
To find a collection point, you can use search engine our website:
To view collection points in your city, click the "Select recyclables and city" button located on the right and select your city. You will be able to familiarize yourself with prices, addresses and telephone numbers, and based on this, choose the acceptance that suits you best.
Attempts to revive the UPS do not always lead to the desired result
UPS acceptance rules
When going to a collection point to recycle your uninterruptible power supply, you must consider the following requirements:
- The device must be unassembled and without damage;
- It is advisable to wipe the outside of the device from dust and dirt;
- During transportation, care must be taken to ensure that the UPS does not fall or be damaged.
We are preparing the IPB for delivery: careful packaging will help protect against damage
When handing over the battery, you do not need to have any documents with you. The monetary reward is paid immediately after the collection point employees inspect the UPS and evaluate its model and quality.
Prices for receiving uninterruptible power supplies
The cost of used UPSs may vary depending on the city and collection point, so it is better to call several collection centers in advance and choose the one with the highest price. On average, a standard uninterruptible power supply costs 53-58 rubles per kilogram.
Many PC users have old UPSs that have expired. A common cause of disability is battery failure. Since replacing with new batteries is unprofitable, and sometimes simply impossible due to the lack of analogues, these devices are simply lying around idle or thrown into the trash.
But you can give a second life to the UPS by making it very useful device- an inverter that converts 12 in the vehicle’s on-board network into the 220 V required for some devices. Despite the fact that the factory version of the inverter will cost a lot of money, this way you will save money and make the right thing out of trash.
So, the first thing to do is remove the old, leaking batteries. They can be easily dismantled by removing the bottom cover and disconnecting the power wires. If there are traces of leaked electrolyte, clean the case from oxidation crystals.
This operation will eliminate further acid leakage and will also significantly lighten the weight of the apparatus.
Changing the connection diagram
Uninterruptible power supplies differ in design, but their operating principle is the same - converting 12 V to 220 V. That is, each model contains a board with electronic converter voltage. That's what we need. But there is one condition: it must be working.
Since the devices that will be connected to this device have a standard 220 V plug, it is necessary to install a regular household socket on the side or rear panel for hidden wiring. It is to this that we solder the output wires from the 220 V converter, which previously fit into special three-arm plugs on the back panel of the UPS.
In the first and second cases, the wires are soldered to those that went to the UPS battery. It is very important to maintain the polarity of the connection. The red wire is positive and the black wire is negative.
Both in the car network and in the UPS, these colors must match. It is best, of course, to check the polarity with a multimeter to be sure.
This connection scheme provides for immediate operation of the device when it is connected. If you want to turn it on via a toggle switch or machine, then simply break the “plus” in the wire coming from the car’s battery and connect one wire to the input and the other to the output of the machine attached to the UPS housing. This cuts off the power to the inverter when needed.
Subtleties at work
It should be understood that such a device will not produce much power. As a rule. it is no more than 150 W, but this is quite enough to connect a small TV, laptop and other low-current equipment.
Why is the car battery not charging from the charger?
