3.6.1 Features and Distributed Architecture of the Power Supply
System
This section describes the features, distributed architecture, and PEM of the power supply
system.
If DC power source is used, connect the DC power cables to the PEM input terminals.
If AC power source is used, use a suitable external AC-DC convertor. The number of rectifier
modules of the AC-DC convertor depends on the system power consumption. The AC-DC
convertor converts AC power to DC power and supplies DC power to the PEMs.
As shown in
having two power inputs. These four power inputs work in backup mode.
