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 56Vdc 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.

AC FAIL: Upon loss of AC line (V input ≤ 90 VAC), this open collector
output goes from low to high before loss of output regulation.
DC FAIL: Upon loss of DC output (V outputs ≤ 49 VDC) this output goes
from low to high.
