The R911201452 (RD52.1-4N-022-L-NN-FW) is a drive system from the Bosch Rexroth RD52 series intended for motor control applications. It operates with a three-phase AC input voltage of 380–480 V and provides a nominal power output of 22 kW. This converter unit does not include a brake chopper and features a built-in mains filter. The device supports optional components such as a frequency converter, current filter feedback, cable damping feedback, 24 V standby power, and 95 mm² terminals. The enclosure carries an IP20 rating. Electrical connectivity relies on large-surface metal contacts, while system operation requires segregated cable routing, proper noise suppression measures, and shielded cables with double-ended grounds. At a 4 kHz pulse frequency, the drive delivers a continuous output current of 43 A and a peak output current of 55 A. Forced air cooling is used, with a required airflow of 0.1 m³/s, and the rated power loss is 0.8 kW. The unit weighs 36 kg. Only qualified personnel should perform maintenance due to the high-voltage nature of the device.
