10. Operating and Protective Functions

◆ 10.1 Basic Operation
(1) Under normal conditions
Basically, the UPS converts AC power from the commercial source (AC input) into
DC power through the rectifier, and reconverts this DC power back into AC power
through the inverter. The reconverted AC power is synchronized with the
commercial source to ensure a stable power supply to the loads. The batteries are
kept continually charged and ready in case a problem (outage or voltage drop) occurs
in the commercial power supply.
