Rectifier Modules and Battery Interface Unit
Each rectifier module operates as an integral part of a complete power system
with battery backup. The modules operate in a redundant, high reliability mode to
provide -48 VDC at 850 Watts to a common power bus.
The Battery Interface Unit (BIU) controls the rectifier modules, manages the
batteries, and reports the status of system power. The BIU provides the Remote
Power Off (RPO) option and battery alarm interfaces for internal and external
alarms.
