The R911276632 (HVR02.2-W010) is a Rexroth Indramat second-generation HVR power supply unit engineered for integration with HDD and HDS drive controllers in multi-axis drive systems. It features an internal air cooling method with a built-in blower and transforms 3-phase AC mains input (380 V to 480 V ±10%) into a regulated DC bus voltage. This unit supports a maximum continuous mechanical power output of 36 kW for connected motors, provides 10 kW power output with a 30 kW peak, and can handle up to 80 kWs of regenerated energy. It functions at ambient temperatures from 5°C to 45°C, with storage tolerances between -30°C and 85°C, operates at elevations up to 1000 meters, and has an IP10 protection class.
