UPS is divided into backup type, online type and online interactive type according to its working principle.
Among them, the backup UPS is the most commonly used. It has the most basic and important functions of ups such as automatic voltage stabilization and power-off protection. Although it generally has a conversion time of about 10ms, it is widely used in the fields of microcomputer, peripheral equipment, POS machine and so on because of its simple structure, low price and high reliability.
Backup UPS power supply is divided into backup sine wave output UPS power supply and backup square wave output UPS power supply.
Backup sine wave output UPS power supply: single machine output can reach 0.25kw ~ 2kW. When the mains power changes between 170V ~ 264v, it will provide users with mains power treated by voltage regulator; When the mains power exceeds the range of 170V ~ 264v, UPS provides high-quality sine wave power supply.
Backup square wave output UPS power supply: different from backup sine wave output UPS power supply, it only provides users with 50Hz square wave power supply.
The online UPS has complex structure but perfect performance, which can solve all power supply problems, such as four-way PS series. Its remarkable feature is that it can continuously output pure sine wave AC with zero interruption, and can solve all power supply problems such as peak, surge and frequency drift; Due to the need for large investment, it is usually used in critical equipment, network centers and other environments with strict power requirements.
Compared with backup UPS, Online Interactive UPS has filtering function, strong anti mains interference ability, conversion time is less than 4ms, and the inverter output is analog sine wave, so it can be equipped with server, router and other network equipment, or used in areas with poor power environment.
