TEB4815 - 4U, 48V, 150Ah LFP

This new Delta 48V battery pack is designed with 150Ah capacity battery cell of lithium-ion iron phosphate chemistry. It provides larger capacity in a compact size of 19” rack-mounted 4U chassis. This pack has RS485 communication and built-in BMS with automatic protection and cell balancing to offer safe and most efficient operation to customers.

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.
