AC/DC Power Supply The load demands on the AC/DC converters are the DC/DC converter and up
to six IGDPS modules (up to three IGDPS modules for SPS drives). The DC/
DC is a fixed load; however, the quantity of IGDPS modules will vary depending
upon the drive configuration and whether SPS modules are used.
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.

DC FAIL : Upon loss of DC output (V outputs ≤ 49V DC) this output goes from low
to high.
Location
The AC/DC power supply is located in the low voltage panel at the top right-
hand section of the drive. A typical low voltage compartment is shown in
Figure 97 .
