This new Delta 48 V battery pack is designed with a 100 Ah capacity battery cell of lithium-ion iron phosphate chemistry. It provides larger capacity in the compact size of a 19” rack-mounted 3U chassis. This pack has RS485 communication and a built-in BMS with automatic protection and cell balancing to offer safe and highly efficient operation to customers.
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.
