Working principle:
The UPS is a multiple proctection power system with inverting output isolation transformer.When mains is normal,UPS will output directly,the battery is charged at the same time.When mains is off or abnormal,the battery will change into AC to output,ensuring the user can get the high quanlity electricity.
