The Bosch Rexroth R911200494 (RD51.1-5N-037-L-D1-FW) is a three-phase AC converter drive controller rated for 500 V AC operation (±10%), delivering a nominal output of 37 kW and 68 A. Peak current capabilities reach 88 A for 1 minute, 116 A for 1 second, and 136 A for 0.5 seconds, with an apparent power of 45 kVA. It is designed without an internal brake chopper and requires forced air cooling; minimum airflow of 0.2 m³/s is essential to maintain ambient temperatures between 0 and 40 °C. Additional features include a 24 V standby power supply for drive parameterization independent of the main AC input, as well as connectivity for the RZC01.1-XT module via a NAMUR terminal strip. Firmware is assigned at the factory.
