The Bosch Rexroth R911200439 (RD52.1-4B-090-L-F1-FW) is a drive controller for induction and synchronous motor applications. This unit integrates a converter with a built-in brake chopper and offers various hardware configurations, including feedback for current filtering, standby power, and connectivity for chemistry modules. It operates with a 3 x AC 380-480 V nominal connecting voltage and supports a rated power output of 90 kW. Designed for ambient temperatures from 0 to 40°C and up to 90% relative humidity, the device requires forced air cooling at a minimum rate of 0.4 m³/s to manage its 2.7 kW heat emission. The controller has an IP20-rated enclosure, weighs approximately 74 kg, and must be used in dust-free environments with proper thermal separation.
