The Bosch Rexroth MPN R911295765 (DKR04.1-W400E-BE73-01-FW) is a converter drive designed for operation on a 3 x AC 400-480V grounded mainline, supporting system frequency variations between 50 Hz and 60 Hz and a control voltage of AC 230V ±10%. It features an external bleeder configuration with brake chopper and rigid DC bus, and incorporates an air cooling method using a built-in blower that dissipates 1.8 kW of heat energy, with a total energy dissipation of 2.5 kW. This model achieves a peak power output of 125 kW at a maximum current of 282 A and supports steady power output ratings of 93 kW at 4 kHz switching frequency (210 A input) and 66 kW at 8 kHz (150 A input). Regenerative operation is rated at 66 kW. The drive operates accurately up to 1000 m altitude and provides an IP20 protection class. The command interface is SERCOS, and it supports digital servo and resolver feedback. Rated current is 400 A, and current capacity can be increased with the use of external bleeder resistors. This device is intended for application in high-power machinery.
