RD52.1-4N-011-D-NN-FW

RD52.1-4N-011-D-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers The RD52.1-4N-011-D-NN-FW AC drive converter from Bosch Rexroth Indramat’s robust RD 500 Drive Controllers line provides a high-performance solution for medium-duty motion control applications. It operates on a nominal connecting voltage of 3 x AC 380-480 V and delivers a continuous output of 11 kW through a compact converter unit. Engineered for precise speed and torque regulation, the device integrates seamlessly into industrial automation systems, offering consistent performance under varying load conditions. Its plug-through cooler mechanism ensures efficient thermal management without compromising cabinet space.

Featuring a plug-through cooler for active heat dissipation, the unit sustains a rated current of 25 A with overload capabilities of 33 A for 60 s, 43 A for 1 s, and 50 A for 0.5 s, ensuring resilience under brief torque spikes. The converter’s unit type is specified as a converter without a built-in brake chopper, simplifying integration where external braking resistors are already in place. Ambient operating temperatures range from 0 ... +40 °C, supporting deployment across standard industrial environments. The graphical operator panel provides intuitive status displays and fault diagnostics, speeding commissioning and maintenance. Firmware versions are available as separate orders to match existing control architectures.

Designed for seamless cabinet integration, the RD52.1-4N-011-D-NN-FW combines a compact footprint with field-proven reliability, minimizing installation effort and service interruptions. Its dynamic overload handling and advanced cooling mechanism extend component life and reduce mean time to repair. Ideal for conveyor systems, packaging machines, and light-duty presses, this drive converter delivers the consistent performance and straightforward commissioning that control engineers demand.
