AC/DC Power Supply
The load demands on the AC/DC converters are the DC/DC
converter and up to six IGDPS modules. The DC/DC is a fixed load;
however, the quantity of IGDPS modules will vary depending upon
the drive configuration.
Description
The AC/DC power supply accepts single phase voltage and produces
a regulated 56V DC output for the DC/DC power supply and the HV
IGDPS modules for the SGCTs. The input and output voltages are
monitored and fail signals are annunciated upon either voltage going
below a pre-set level.

DC FAIL: Upon loss of DC output (V outputs ≤ 49 VDC) this output goes
from low to high.
