The Bosch R911200048 (RD52.1-4B-005-L-V1-FW) is a converter-based drive controller that includes a built-in brake chopper and supports an AC input range of 380–480 V or 200–230 V, three-phase only. The unit delivers a rated motor output of 5.5 kW at 380–480 V AC and 2.8 kW at 200–230 V AC. A standby power feature allows operation of control electronics and drive parameterization via a separate 24 VDC power supply when the main AC input is not present. The device incorporates a line reactor and interference suppression filter to reduce AC line harmonics. Forced air cooling is required, and optimal performance is maintained in ambient temperatures from 0 to 40 °C. With an IP20 rating, installation inside a control cabinet is necessary. Firmware is not included.
