RD52.1-4B-132-F-NN-NN-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-132-F-NN-NN-NN-FW from the RD 500 Drive Controllers series is a high-performance AC drive converter engineered for demanding industrial applications. It accepts a nominal connecting voltage of 3 x AC 380-480 V (with compatibility up to 500 V AC) and delivers a rated power of 132 kW through a converter with a built-in brake chopper. This controller employs forced air cooling with integrated liquid circulation to maintain optimal thermal stability under continuous duty. It features advanced field-oriented vector control for precise torque and speed regulation across a wide operating range.

All electronic components must be installed and stored in a clean, dry area between –25 °C and +70 °C; the permissible ambient temperature for operation is 0 °C to +40 °C. Relative humidity must not exceed 90 % and condensation is strictly prohibited. Airborne dust must be filtered out to protect sensitive power electronics, and adequate clearance around the drive ensures proper heat dissipation to prevent thermal derating. Above 55 °C, the RD52.1 output is automatically derated to 70 % of its nominal 132 kW, and elevation above 1 000 m reduces output by 17 % at 2 000 m.

Weighing approximately 128 kg shipping weight, this converter is designed for global distribution and arrives with a one-year warranty. Only trained and qualified personnel should handle, install, commission, operate, or maintain the unit to ensure compliance with safety and performance standards. With mains filter integration and robust construction, the RD52.1-4B-132-F-NN-NN-NN-FW drive converter offers reliable power control for pumps, fans, compressors, and other heavy industrial loads.
