(1) Cosel power supply output is 57V DC, Pioneer power supply output (Heatpipe drives only) is 56V DC.
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.
The AC/DC power supply accepts single phase voltage and produces a
regulated 57V DC
(a)
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.

(1) Cosel Power Supply output is 57V DC, Pioneer Power Supply output is 56V DC
DC FAIL: Upon loss of DC output (V outputs ≤ 49V DC) this output goes from
low to high. 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 115
