1. Introduction
This series of UPS is an online sine wave uninterruptible power supply system with bypass
maintenance switch, which can provide reliable and high-quality ACpower for your precision
equipment. It can be used in a wide range, from computer equipment, communication system
to industrial automatic control equipment. Because of its online design, it is different from the
backup ups. It continuously adjusts and filters the input voltage. When the power supply is
interrupted, it will providethe backuppowerfromthe backupbattery without timeinterruption.
In case of overload or inverter failure, the UPS switches to the bypassstate and be powered by
the mains.If theoverloadiscleared, the UPS will automaticallyswitchbackto the inverter power
supplystate.
