TEB4815

Overview

The pack application is developed for Telecom equipment power backup. Under normal condition, grid AC power supplies to rectifier module and the Telecom loads and also charge battery pack.

When the AC power failed, rectifier module stop power supply to loads, the battery serves for Telecom equipment to ensure the Telecom equipment operation normally; when the AC power is switched on again, power from rectifier module to Telecom equipment recovered and charge the battery pack back to backup status.
