The R911288921 (RD52.1-4B-001-L-V1-P1-L1-FW) is a Bosch Rexroth RD 500 series three-phase converter with a built-in brake chopper, supporting a nominal connecting voltage of 3 x AC 380–480 V and a rated output power of 1 kW. The device features a 24 V DC standby power option for maintaining control electronics operations independent of main input power, enabling uninterrupted parameterization tasks. It is equipped with a primary filter for AC voltage stabilization and recommends using a floating standby power supply through connector X83 to prevent ground loops. The converter employs forced air cooling for continuous operation in ambient temperatures from 0 to 40°C, with an output derating of 2.5% per °C up to 50°C. Drive system firmware is not included. Observe safety instructions detailed in the product manual.
