(1PCS) Amaron 650VA Old Refurbished Tested PCB

1. The Amaron 650VA Home UPS (Uninterruptible Power Supply) is used in an inverter.

This PCB is the brain of the inverter and performs the following important functions:

 

AC to DC Conversion (Charging): When mains power is available, this PCB converts the AC supply to DC to charge the battery.

 

DC to AC Conversion (Inverting): When mains power is cut off (power outage), this PCB converts the battery’s DC power to the 220V/230V AC power needed to run household appliances.

 

Protection and Control: It protects the inverter and battery from conditions such as overload, short circuit, over-charging, and deep discharge, and controls the function of the entire system.

 

Status Indication: The components on it ensure that the inverter is functioning properly and provide indications such as battery level and load status.
