7.1 85-264VAC is supplied directly to each of the rectiers which produce a nominal
-48VDC, +24VDC or +12VDC output.
7.2 Following a current shunt to measure the rectier current, the rectier DC output
is fed to the battery terminals via the LVD (Low Voltage Disconnect, current shunt
and a 100A circuit breaker.
7.3 The rectifier DC output is also fed to the loads via up to 5 circuit breakers
(conguration A) or 10 fused circuits (conguration B).
7.4 The management unit monitors and controls the rectiers via an I²C interface and
also checks the status of the DC load and battery breakers/fuses.
7.5 The management unit monitors external sensors and provides alarms.
