TEB4810

Overview

The pack application is developed for telecom equipment power backup. Under normal conditions, grid AC power supplies to a rectifier module and the telecom loads and also charges a battery pack.

When the AC power failed, the rectifier module stops power supply to loads, the battery ensures the telecom equipment operates normally. When the AC power is switched on again, power from the rectifier module to the telecom equipment is recovered and it charges the battery pack back to backup status.
