UPS power is divided into three types according to the working principle: backup, online and online interaction. Among them, the most commonly used ones are backup UPSs, such as the four-way HO series and SD series, which have the most basic and most important functions of UPS such as automatic voltage regulation and power failure protection, although generally have a conversion time of about 10ms, the United States. The mountain AC series rack-mounted UPS inverter output AC is a square wave instead of a sine wave, but because of its simple structure, it has the advantages of low price and high reliability, so it is widely used in online UPS of microcomputers, peripherals, POS machines, etc. The structure is more complex, but the performance is perfect, can solve all power problems, such as the four-way PS series, its remarkable feature is that it can output pure sine wave AC power with zero interruption, and can solve all power problems such as spikes, surges and frequency drift; Due to the need for large investments, it is often used in power-critical environments such as critical equipment and network centers. In addition, four-way, APC and other manufacturers also provide online interactive UPS, compared with the backup type, online interactive with filtering function, strong anti-communication interference, conversion time is less than 4ms, the inverter output is analog sine wave, so can Equipped with network equipment such as servers and routers, or used in areas with poor power environments.
