To be healthy, one needs to eat well. The situation is similar with computers: a PC requires repairs less often if it receives power of 220-230 V. Going beyond the acceptable voltage range negatively affects the well-being of computer equipment. Another reason to buy the UPS Eaton 5S 1000VA is the guarantee of data preservation in case of a power outage. You will be able to calmly save information to the hard drive and properly shut down the operating system. The 5S is a relatively new line from the American company Eaton. It includes several models that differ in power. The 1000VA is a suitable option for providing quality power to a gaming computer, two office PCs, or a small server. **Design** The UPS comes in a discreet black case. The ventilation openings are positioned to allow for both vertical and horizontal installation of the device. The width is only 9 cm, so the UPS can be squeezed into a narrow niche if necessary, as long as the ventilation grilles are not blocked. **Device** The design of the UPS includes an AVR system. During minor voltage fluctuations, the UPS operates in stabilizer mode, not engaging the battery unnecessarily. As a result, the batteries last longer. The case houses 2 batteries that work in tandem. To access them, simply unscrew one screw and remove the cover on the front panel. **Connectors** On the back side: - 1 input socket; - 8 output sockets, 4 of which are connected to the battery; - a protective switch; - 2 connectors for monitoring voltage in low-current networks; - USB for connecting the device to a PC. USB and telephony are often no longer connected to the UPS. This functionality is usually left unused, but it is standard for this class of devices. **Advantages** - A maximum load of 1000VA allows you to connect two closely located computers without overpaying for two low-power UPS units. - Presence of AVR. - Eight output sockets provide the ability to connect not only PCs but also other equipment, such as a modem, printer, or scanner. - Compact size. - The brand's authority is beyond doubt. - Sound and light signaling. - Thanks to self-testing, the device will alert you when it's time to replace the battery. Eaton 5S is a great choice for home and office, providing reliable protection for computer equipment.
