What is the name of the device that provides the server with power?
In principle, the UPS is a power electronics device incorporating digital and analog circuits, automatic control inverters, and maintenance free storage devices;Functionally, UPS can effectively purify the city power when the city power is abnormal. It can also supply power to the computer and other equipment for a certain period of time when the city power breaks suddenly, so that you can have enough time to cope with it;From the use, with the coming of information society, UPS is widely used in the information collection, transmission, processing, storage and application to each link, its importance is increased with the increasing importance of information applications.
The US is the most commonly used backup UPS, such as the four HO series and SD series, it has automatic voltage regulator, power protection UPS the most basic and most important function, although the general conversion period of about 10ms, inverter output AC square wave and non sine wave, but due to the simple structure has the advantages of low cost, high reliability, so it is widely used in computer peripherals, POS, machine etc.;The on-line UPS structure is complex, but the perfect performance, can solve the problem of power supply, such as the four PS series, its remarkable characteristic is to continue zero interrupt output pure sine wave AC power supply, can solve all the problems of the peak surge, frequency drift; due to the need for greater investment, usually in the key equipment and network center the electric power demanding environment application;
UPS is the abbreviation of uninterruptible power system, which is an important external equipment to provide continuous, stable and uninterrupted power supply.
You should say is UPS (uninterruptible power supply system), installed between the power and the server, in the case of external power failure, you can automatically switch to the UPS, the internal battery powered, and not to suddenly lose power, resulting in data loss
