AC and HVDC Power Supply
As shown in Figure 1-42, after the external power is input to PMs through PEMs, the PMs
convert power and output the power to the power supply backplane. Each PEM provides four
channels of power inputs (with two partitioned into area A and two partitioned into area B) for
four PMs. There are 8 PMs on the device.
