When the mains power is normal, one mains power will charge the battery through the rectifier, while the other mains power will be initially stabilized by the automatic voltage regulator to absorb part of the power grid interference, and then directly provided to the user by the bypass transfer switch. At this time, the battery is in the charging state and turns to the floating charge state after knowing that the battery is full.

When the grid voltage or grid frequency exceeds the input range of UPS, that is, under abnormal conditions, the input of AC is cut off, the charger stops working, and the battery discharges. Under the control of the control circuit, the inverter starts to work, making the inverter generate 220V and 50Hz AC. at this time, the UPS power supply system is converted into battery inverter to continue to supply power to the load.

Features: simple structure, low price, low noise, but most of the time, the load is a "low-quality" sine wave power supply with slight voltage stabilization. The conversion time is long, and the inverter of backup UPS uninterruptible power supply does not work often. Therefore, it is easy to form invisible faults if it does not grasp the dynamic status of the inverter. Suitable for less important single PC.
