Among them, standby UPS is the most commonly used one, which has the most basic and important functions of UPS, such as automatic voltage stabilization and power failure protection. Although the conversion time is generally around 10ms, the alternating current output by the inverter is square wave rather than sine wave, but because of its simple structure, low price and high reliability, it is widely used in microcomputer, peripherals, POS machines and other fields.
On-line UPS has complex structure, but perfect performance, which can solve all power supply problems. Its remarkable feature is that it can continuously output pure sine wave alternating current, and can solve all power supply problems such as peak, surge and frequency drift. Because of the large investment, it is usually used in key equipment, network center and other environments with strict power requirements;
In addition, there are many online interactive UPS. Compared with standby UPS, online interactive UPS has filtering function and strong anti-interference ability. The conversion time is less than 4ms, and the output of the inverter is analog sine wave, which can be equipped with network equipment such as servers and routers, or used in areas with harsh power environment.
