6.6 GEPS4845 Power System
This topic describes the function, power supply principles, and front panel of the GEPS4845
power system, and provides the specifications of the GEPS4845 power system.
Function
The AC-powered cabinet uses the GEPS4845 power system to convert the 220/110 VAC into
-48 V DC and then distributes the power to each load. The GEPS4845 power system can
connect to two sets of batteries.
NOTE
Both the rectifier units of GEPS4845 and the two sets of batteries work in the load-balancing mode. The
rectifier units are hot backup for each other.
