AC/DC Power Supply
7000 "A" Frame
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 that power the SGCTs. The input and output voltages are
monitored and fail signals are annunciated upon either voltage going
below a pre-set level.
