a. The individual 05100PS power supply unit will source +10.000 Vdc at 100 A. How-
ever, the standard configuration of this series of power supplies includes the Model
601 Energy Absorber to provide bipolar operation. The 05x00-430-601 series of
power supply systems provides a maximum available voltage to the load of ±5.000
Vdc at multiples of 100 A, up to 500 A depending on the system selected.
b. The Kepco BOP power supplies are limited to only one-half the output voltage
range since the supplies are designed to safely dissipate only one-half the rated
power output.
c. The values shown for the Custom... option are defaults. The user should enter the
appropriate values within the respective submenus. Custom values, once entered,
are saved in nonvolatile memory.
