How to choose the right UPS and what to pay attention to

UPS type. Uninterruptible power supplies are usually divided into three main types depending on the topology:

backup UPSs are the simplest and most affordable. When the power supply starts to go bad, such a UPS simply switches the computer to battery operation. Unfortunately, active use quickly destroys the batteries. In addition, switching is not always fast enough to fully protect the connected equipment.
line-interactive UPSs are already equipped with a transformer that smoothes out voltage surges in the network. Accordingly, they switch to battery power only as a last resort. Such devices are more expensive than conventional backup UPSs, but they also provide protection at a higher level.
Double conversion UPSs in this triad are the most expensive, but also the most efficient. They use the capabilities of the battery and the voltage converter at the same time. Thanks to this approach, devices connected to the UPS are almost absolutely safe.

Power. This parameter must correspond to the power consumed by the devices connected to the UPS. At the same time, you do not need to buy an uninterruptible power supply, because some of the power is inevitably lost. It is advisable to take a UPS with a power reserve of 20-30%.

Type of power output connectors. Most often, UPSs have two types of output connectors: CEE 7 - a regular Euro socket; and IEC 320 C13 - three-pin power connector for PC.

Input voltage range. Shows at what network voltage values the UPS switches from transformer mode to battery operation. The wider it is, the less often the device will use the built-in battery and, accordingly, wear it out less.

Input frequency. The frequency of electrical current with which the UPS can operate. Usually this is the standard 40-60 Hz.

Output voltage stability. The ability of a UPS to maintain a certain output voltage while operating in transformer mode. This parameter directly depends on the accuracy of the UPS, measured as a percentage.

Charging time. The smaller it is, the faster the batteries built into the UPS are charged from the network.

Operating time at full load. The higher the battery capacity and the lower the power consumption, the longer the UPS is able to independently power the equipment connected to it. In order to quickly save data and safely complete work, 5 minutes is usually enough.

Switching speed. The smaller it is, the better, because this parameter shows how quickly the UPS switches from operating in transformer mode to autonomous power supply. Measured in milliseconds.

How to choose an uninterruptible power supply

After getting acquainted with the presented nominees, all that remains is to decide which one to buy. We recommend defining the operating conditions in advance, comparing several characteristics with them - device type, power, presence of power connectors, battery life.

Uninterruptible power supplies may differ in the operating mechanism, design and principle of operation. The most in demand are 3 types of uninterruptible power supplies:

backup models are the most inexpensive models, which are appropriate in conditions of rare power outages; they will withstand no more than 5-10 minutes of operation before discharge;
interactive - or linear-interactive (Smart Ups) with an AVR stabilizer, it turns off only when the voltage deviation is high;
double conversion - expensive “online” UPSs that provide the best quality of power supply without the risk of voltage failure even when switching to backup power.

The first option is universal; it will cope with minor power surges, but it is more of an uninterruptible power supply for the home. The second is optimal for home/office use. The third gives stable performance in any conditions.

Power

The manufacturer indicates this characteristic in units of measurement “VA”. This is the maximum total power produced by the equipment connected to the device. Using current clamps and a multimeter, you can determine this parameter for different equipment used at maximum load.

Power connectors

Another important selection parameter is the number and types of connectors on the UPS case. It is important to consider how many devices will be used. Most often, manufacturers use the following interfaces and slots:

standard socket for household appliances;
battery powered socket;
a slot through which you can control a PC;
slot for connecting telephone and network lines;
socket connecting the UPS to the mains;
special connectors for self-diagnosis and monitoring (COM, USB).

The most expensive modifications are those that include all of the listed slots at once. This means that the list of situations where they will be useful is extensive.

Battery life

The third determining factor for the buyer is battery life. A lot here depends on the type of battery, its capacity, and the total power of the connected consumer devices. The number must be written in the instructions. With rapid discharge, in 5-10 minutes the battery is capable of delivering 20-30% of the installed nominal capacity.

Which UPS is better to buy?

To choose the most suitable UPS, you should decide on the initial data: the quality of the current in the electrical network used, the number and type of devices that will be connected to the UPS, the expected cost of the device, etc.

All uninterruptible power supplies are divided into:

reserve;
interactive;
inverter

A backup UPS will be a good solution when power surges are rare and only 1-2 devices need protection. When purchasing such a device to protect a PC, you need to check the compliance of the minimum and maximum voltage values of the device and the consumer in order to prevent unnecessary UPS operations in situations where the connected device can still work.

If the network is unstable, the voltage drops to 180-190 V, and a large number of devices need to ensure uninterrupted operation, it is better to use an interactive UPS. It has full functionality of backup devices and, in addition, allows you to regulate the voltage at the network output. A device of this type essentially consists of a backup UPS and a stabilizer.

The best quality power supply can be obtained using inverter (on-line) UPSs, the battery of which is constantly connected to the network. Due to this, any voltage dips during transitions to autonomous mode are excluded.

The most important technical characteristics that can influence the choice of UPS are:

Output power, which determines the total power of all consumers connected to the device.
Battery life - the higher this indicator, the more time the user has to, for example, shut down work on the computer without losing data.
Type of output connectors - these can be sockets of the older IEC-320-C14 type or the Euro standard CEE 7/4.
Control interface – USB, LAN, RS-232, SmartSlot.

Equipping with additional functions also plays an important role. These include:

Possibility of voltage adjustment;
Cold start;
Connecting an external battery;
Bypass (direct connection);
Display, etc.

Based on the installation method, UPSs are divided into conventional (floor-standing), wall-mounted, and server (rack-mounted). For some consumers, an important parameter is the voltage shape at the output of the device, which can be sinusoidal or stepped.

Which uninterruptible power supply is better?

Still haven't decided what to buy from the list presented? Vyborexperta.ru does not give an unambiguous recommendation on what to choose. But a comparative analysis of advantages and weaknesses highlights the brightest representatives of the rating:

Ippon Back Power Pro II 600 – a compact and budget interactive unit with USB and the ability to charge gadgets;
Powercom Raptor RPT-600A Euro – the longest battery life, removable, replaceable battery and informative screen;
Bastion Teplocom-100+ is the best solution for maintaining the stability of heat supply systems;
Spider SPD-1000N – case with the largest number of connectors, Bypass mode;
Back Verso 800 New – the best solution for protecting the telephone network, speed and different slots;
WOW-300 – automated AVR functioning system, different installation methods;
CyberPower OLS2000EC is the review leader in terms of functionality and endurance, 4 power sources at once, energy-saving ECO mode.

For home use, with frequent network outages and fairly stable voltage, backup modifications are appropriate. If you need protection from frequent power surges, linear-interactive devices can cope with this problem by leveling out the surges. On-line UPSs can protect important servers and systems without shutting down.

UPS for computers and servers

As mentioned above, initially uninterruptible power supplies began to be used for computers and servers. Such equipment differs from other types of UPS, so it is worth distinguishing them as a separate type. What are their features?

When choosing an uninterruptible power supply device for PCs and laptops, you need to accurately measure the power consumption - of course, you should have a meter for this purpose. And although it is not that expensive, it does not always show the correct values. How to understand the electricity consumption of a specific device? For simplicity, you can use the following table of individual device power values:

CRT monitor: 80 -120 W;
LCD monitor: 30-70 W;
Work (office) computer: 100-150 W, now more often than 200 W;
Multimedia computer: 200-250 W, today often around 350 W;
Gaming computer: 250-350 W, often up to 400-500 W;
Laptop: 50-80 W;
Netbooks and small laptops: 20-50 W;
Graphics station: 250-400 W, and in some cases 500 W;
Network server: 300-600 W, but there is a lot of variety here.

Of course, you can just read the electrical power value on the device packaging, but in practice, computers only need such large values to start. In reality, power consumption values depend on many different factors, and modern equipment often requires more power to operate at acceptable performance.

This can also include the power of switches, hubs, USB-powered peripherals, and even flash drives and storage devices. Therefore, rounding the power value “by eye” is a big mistake. If you are not sure which device is suitable for your home computer, use a 600VA UPS - it is suitable for almost all types of PCs.

Recommendations for choosing a UPS for a computer

When choosing a UPS for computer equipment, we advise you to adhere to the following recommendations:

Use multiple UPSs . One uninterruptible power supply with a power of 600 W or more may not be enough. If your village experiences frequent power failures, it is better to have a spare device, and since the price difference between powerful and small UPSs is small, it is logical to choose the same equipment;
The shape of the output voltage - paradoxically, many models even of expensive computer equipment do not have this function. The cleaner the voltage sine wave between the outlet and the PC, the longer your computer will last. In order to smooth out voltage drops, you can purchase any type of power supply with an approximate sine wave;
Surge protectors are generally a must have (approx. obligatory) equipment for any important equipment in the house. Good models of uninterruptible power supplies already have a surge protector as standard. But for cheap ones you will have to buy it separately;
Battery life - here, alas, you shouldn’t expect big numbers: most UPS models for computers can keep the device running for only 5-10 minutes. This is enough time to save the work done and turn off the PC. But for laptops, UPSs are, in principle, not needed, because it will continue to operate even when the electricity is turned off (simply by switching to battery power). On the other hand, the UPS itself is not intended to be used as an emergency power source during normal operation, but only to ensure the safe recording of all files;
Number of output sockets - there should be at least 2, although the more the better. However, it is worth comparing with the size of the power supply itself, since each outlet increases the size and weight of the equipment, and in small rooms it is often a problem where to place such a huge unit.

If you are looking for a cost-effective solution to protect several computers in your home, it may be to purchase one high-power UPS (it has less energy loss).
