The Bosch MPN R911201456 (RD42.1-5R-084-L/S135) is a regenerative power supply unit engineered for operation with a 3-phase 500V AC input at 50/60 Hz. The unit supports a DC link voltage of 660V and delivers an output power of 84 kW. It is rated for a current of 160 A and can deliver a peak current of 240 A for up to 60 seconds. Rated and peak output at the input side are approximately 105 kW and 160 kW respectively at 500V AC. A 200 A fuse is recommended for circuit protection. At rated output, line supply current is 150 A and power losses are approximately 1.5 kW. The device uses forced air cooling, requiring 0.2 m³/s airflow. It is classified in size class F with an IP20 protection rating. The permissible storage temperature is -25 to 70 °C, and operating temperature is 0 to 40 °C, with relative humidity below 90%. For installation above 1000 meters altitude, derating must be applied.
