The Bosch Rexroth MPN R911203254 (RD51.1-5B-003-D-CF-FW) is a modular three-phase current drive system designed for control of both synchronous and induction motors. It uses a frequency-controlled U/f curve control methodology, enabling proportional output of frequency and voltage for a wide range of non-servo applications such as extruders, ventilators, and conveyor belts. The system features an integrated regenerative power supply module, internal braking chopper, plug-through cooling (for <= 110 kW), and supports external connection for RZC01.1-XN and 24 V stand-by power. It is rated for a nominal connecting voltage of 3 x AC 500 V (±10%) and a rated power of 3 kW. Compliance to EMC standards for noise emission and immunity is provided, with an environmental classification of 3K3 per DIN IEC 721-3-3. Operational temperature range is specified from 0 to 40 degrees Celsius.
