We invite you to familiarize yourself with the characteristics of the selected uninterruptible power supplies, as well as select a suitable UPS from the general catalog.

Pure sine wave, output voltage regulation, light weight, quiet.
2 sockets.

The inexpensive Eaton 5E 700 USB DIN Gen2 UPS provides optimal output power parameters (pure sine wave), which allows you to connect not only a PC, but also equipment sensitive to interference and distortion (audio equipment, medical devices, testers, LED lighting, heating boilers). The two-stage AVR handles input voltage from 140 to 300 V. The USB port and proprietary utility will ensure timely monitoring and adjustment of parameters.

High build quality increases the comfort of use, as the UPS does not emit extraneous sounds, and the overall noise level does not exceed 25 dB. Its weight is only 4.4 kg, so moving it around the apartment or house to the right place will not be a problem even for a child. A 9 Ah battery guarantees decent autonomy (about 14 minutes) for one PC to correctly complete all processes. The manufacturer has provided only 2 output sockets, so connecting anything other than the system unit and monitor will be problematic.

Pure sine wave.
Terminal connection, 1 socket.

The RITAR SK-500VA uninterruptible power supply provides the autonomy that the user needs. There is no standard power supply, and the design provides for the connection of an external battery. The recommended capacity is up to 100 Ah. The UPS is sufficient to supply power to equipment with a capacity of up to 300 W for several hours, which is especially important for servers and network equipment. The line-interactive system responds in 4 ms and guarantees stabilization of the input voltage within 145 - 275 V. It is worth noting that standard terminals are used to connect the battery, not alligator clips, which limits the choice. Only one Euro socket is available at the output, so an extension cord or a surge protector will be required.

RITAR SK-500VA creates a correct sine wave at the output for safe operation of all consumers. The model is compatible not only with computer and office equipment, but also guarantees stable start-up and operation of gas and solid fuel boilers, pumps, sensitive audio equipment. The UPS is equipped with overload and short circuit protection, controls the battery charge level. All information is displayed on the display. The case has a cooler for cooling components, the speed is adjusted automatically depending on the temperature.

8 sockets, USB for charging gadgets, display, output voltage regulation, impulse protection, switching in 4 ms.
Not found.

The Powercom Spider SPD-750U LCD UPS offers universal mounting (desktop, floor, wall) in vertical and horizontal positions. All controls, indicators and sockets are located on the front panel for easy connection and control. The backlit display shows basic information: voltage, battery status, operating mode. The battery has a separate compartment with a cover, so it is easy to replace without having to disassemble the case.

The user has a total of 8 Euro sockets, which provide output voltage stabilization within 220 - 240 V depending on the settings. 4 sockets are connected to a capacious 9 Ah battery and allow the PC and peripherals to operate autonomously, including in cold start mode. If necessary, you can recharge a laptop, smartphones, flashlights. When powered from the main network, gadgets are charged via 2 USB 2.0 connectors with a maximum current of 2.4 A. Switching to the battery is carried out in 4 ms, eliminating interruptions in the operation of sensitive equipment.

The proprietary utility allows you to make changes to the settings, control the operating parameters and even create a schedule after connecting to a PC via the USB-B interface. The UPS provides comprehensive filtering from electromagnetic interference and pulse surges. Additionally, RJ-45 ports are implemented to prevent failure of network cards and routers in the event of a lightning strike to the provider's equipment.

Interactive UPS, 4 sockets, cold start, quiet operation.
Strong smell from new UPS.

The Powercom RPT-1025AP Schuko line-interactive UPS has an effective output power of 615 W. That is, it is designed to service one or two workstations. Inside it are two batteries with a capacity of 7 Ah each. The manufacturer claims that this is enough to ensure autonomous operation of a standard home or office PC (consisting of a system unit and a monitor with an average diagonal) for 7-10 minutes in the event of a power outage. In addition to working as a backup power source, the device functions as a voltage stabilizer. It automatically detects voltage surges and sags in the network and corrects them on the fly, providing the connected equipment with high-quality current.

All connectors are located on the back of the UPS. There are 4 sockets there, to which you can connect power consumers (each of them is connected to the reserve and can be used for a "cold start"). Next to them there is a pair of RJ45 connectors (the UPS can provide protection for a telephone or modem line from impulse interference) and a USB port. Through this port, you can control the UPS operation from a computer with the appropriate software installed (for example, set up a schedule for turning the device on and off) or monitor the main operating parameters (input and output voltage, load, battery charge, etc.).

Users note that Powercom RPT-1025AP Schuko operates quietly even under full load. However, reviews of Powercom UPS, including this model, contain complaints about strong smells of plastic and varnish. Be prepared for the fact that the new UPS will emit an unpleasant "Chinese" aroma for some time (from a couple of days to a couple of weeks) (although Powercom is actually a Taiwanese company).

The APC Back-UPS 750VA BX750MI-GR provides reliable protection of equipment from voltage surges in the network, as well as short-term autonomous operation (about 7 minutes at a load of 50%) when the main power supply is disconnected. The rated output power of 410 W is enough to connect two typical PCs or other equipment with the corresponding consumption characteristics. For this purpose, 4 backup F-type (Euro) sockets are provided. RJ-45 connectors are also implemented to filter interference and distortion on the Internet cable, eliminating damage to network equipment at home or in the office. The UPS has all the standard protection features and an additional barrier against impulse surges. The automatic fuse quickly responds to critical deviations in the power supply and does not require replacement to restore functionality.

APC Back-UPS 750VA BX750MI-GR operates efficiently with an input voltage of 140 – 300 V. The system automatically responds to deviations, choosing the optimal scenario. The switching time to the battery of 6 ms ensures stable power supply for most equipment, including computers. The USB port allows you to synchronize the UPS with a PC, monitor and change system parameters using a special application. Considering the characteristics, the retail price seems a little overpriced.
