Backup battery system for power towers

Product Overview

With its integrated structure design, intelligent BMS monitoring, and standardized cabinet installation, the WBY 48V series ferritic phosphate batteries can provide a reliable backup power supply for access network equipment, remote switch, mobile communication, transmission equipment, emergency power supply and other systems. This product has the communication function and can realize multiple groups in parallel, providing a flexible and effective solution for the power system of communication operators.

 

Operating Principle

Operating principle of the communication lithium iron phosphate battery system: After the mains input 220V is processed by the rectifier power module to output 48V. In the case of normal operation of power grid, the rectifier power module provides the power for the system and charges the battery system at the same time; when the power grid is powered off, the battery system provides the power to ensure the normal operation of the DC power system and achieve uninterrupted power supply. The power supply provides the secondary power-off function. When the battery voltage is too low, the power supply can be cut off to protect the battery.
