UPS classification

UPS is divided into backup , online and online interactive categories according to the working principle .

Among them, our most commonly used is a backup UPS, which has the most basic and most important functions of UPS, such as automatic voltage stabilization and power failure protection . Although it generally has a conversion time of about 10ms, it has a simple structure and is cheap and reliable. high , etc., it is widely used in the field of computer peripherals, POS machines. Backup UPS power is divided into backup sine wave output UPS power and backup square wave output UPS power. Backup sine wave output UPS power supply: stand-alone output can achieve 0.25KW ~ 2KW, when the mains power changes between 170V ~ 264V , provide the user with the mains power processed by the voltage regulator; when the mains power exceeds the 170V ~ 264V range Only UPS provides high-quality sine wave power. Backup square wave output UPS power supply: Unlike the backup sine wave output UPS power supply, it only provides users with 50Hz square wave power supply.

On-line UPS structure is more complex, but improve performance, solve all power problems, such as Stone PS series, especially its remarkable point is the ability to continue to zero interruption pure sine wave AC output, can solve spikes, surges, frequency drift, and all Power problem; due to the large investment required, it is usually used in critical power and network center environments where power is critical .

Online interactive UPS , compared with backup, online interactive has filtering function, strong anti-interference ability, conversion time is less than 4ms, inverter output is analog sine wave, so it can be equipped with server, router and other network equipment, or Used in areas with severe power environments.
