Regenerative Power Supply Specifications
Because of the larger current requirements for motors from 45 to 75
kW a master 37 kW regenerative power supply (RPS) and a slave 37
kW RPS are required. Each master or slave RPS requires its own line
reactor, harmonic filter and varister. The master and slave RPS units
are designed to share the current loads equally so incoming AC fuses
and wiring should be sized accordingly.
