High Capacity Backup Batteries

For 48Vdc power equipment requiring extended backup time, SEI offers a series of high Amp Hour capacity 48 Volt battery systems. These systems consist of a battery cabinet and 4 high capacity telecom quality stationary batteries. Available capacities include 25 Amp Hours, 35 Amp Hours, 65 Amp Hours, and 90 Amp Hours.

Charge current is limited to the manufacturer's requirement of C/4 or less. The output is protected from a short circuit with a 15 Amp fuse. The battery cabinet and battery strings may be ordered individually as replacement parts or together for new systems. The cabinet is mounted on four industrial castors for ease of movement. Two castors are lockable for secure placement.
