The Bosch Rexroth MPN R911203476 (RD51.1-5N-200-R-V1-FW) is a vector control device from the RD 500 series, designed for use with three-phase drive systems. It supports a nominal connecting voltage of 3 x 500 VAC (±10%), with a rated power of 200 kW. The unit operates with a peak current capacity of 312 A for one minute and 408 A for one second, and belongs to size class G. Cooling is achieved by liquid circulation using an internal pump, requiring a coolant mixture of antifreeze and tap water and careful temperature management to prevent corrosion. The device features 24 V external standby power and does not include a built-in brake chopper. Compliance with relevant EMC regulations is ensured. Proper installation requires a 100 mm clearance around the unit and protection from condensation and corrosive gases.
