RD52.1-4B-200-F-FM-FW

The Bosch Rexroth Indramat RD52.1-4B-200-F-FM-FW from the RD 500 Drive Controllers series delivers robust power conversion with a nominal connecting voltage of 3 x AC 380-480 V and a rated power of 200 kW. This converter with a built-in brake chopper supports a pulse frequency of 4 kHz at full motor output and reduces to 160 kW at 8 kHz pulse frequency for fine control. Its forced air cooling with integrated liquid circulation ensures stable thermal management under heavy-duty cycles. Compact yet durable, this module integrates seamlessly into high-demand process and machine tool environments.

Engineered for reliability, the drive’s brake chopper continuous power rating of 40 kW and peak power of 100 kW handle regenerative energy with ease. The unit weighs 180 kg and is designed for vertical mounting, optimizing cabinet space while maintaining an IP20-equivalent protection level in clean, dust-free conditions. Ambient specifications include an operating temperature range of 0 to 40 °C, up to 90% relative humidity, and altitude limits from 0 to 1 000 m. Electrolytic capacitors in converter and supply modules retain full performance after storage at or below 40 °C for up to two years.

Beyond core power conversion, the RD52.1 integrates a frequency converter without output chokes and a feedback current filter for enhanced waveform fidelity. Installation requires standard air filters to maintain dust-free intake and adherence to specified humidity levels. Globally shippable with a one-year warranty, this drive controller meets the rigorous demands of chemical processing, packaging machinery, and assembly systems where precision and uptime are critical.
