When UPS is in normal working mode, AC goes through the filter and the harmful waves
are filtered. After that, AC charges the battery and meanwhile, passes UPS AVR and the
filter and provide power for the equipment.
AC Failure
When AC fails, the battery will supply power to the inverter and then passes filter and
provide power for the equipment, ensuring the continuous power supply.
