RD42.1-5R-084-L/S135

The Bosch Rexroth Indramat RD42.1-5R-084-L/S135 from the RD 500 Drive Controllers series is manufactured by Bosch Rexroth Indramat. This Regenerative power supply module delivers a rated output of 84 kW at a 3-phase AC 400 V input and supports a rated current of 160 A. The unit accepts a nominal input voltage of 500 V AC at 50/60 Hz and rectifies to a DC-link voltage of 660 V DC, enabling seamless energy feedback. It accommodates a peak DC current of 240 A for 60 s and a peak line output of 160 kW, ensuring robust performance under transient loads.

Efficient thermal management is provided by forced air cooling with a minimum airflow requirement of 0.2 m³/s and a recommended 200 A fuse on the AC side. Despite delivering high power, the module maintains low losses—approximately 1.5 kW at rated output—and conforms to IP20 ingress protection within a size class F enclosure. The design handles line-side currents up to 150 A at 500 V AC and supports continuous operation with stable performance. Robust internal filters and regenerative topology minimize harmonic distortion, making the device suitable for energy-critical applications.

The RD42.1-5R-084-L/S135 is specified for ambient temperatures from 0 to 40 °C with relative humidity below 90 %, and storage conditions from –25 to 70 °C with limited temperature swings. At altitudes above 1 000 m, output must be derated according to the product documentation—dropping to roughly 83 % of nominal at 2 000 m. Backed by a one-year warranty, this drive controller is ready for global deployment in diverse industrial environments.
