(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
(1)
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. 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
