RD52.2-4B-007-D-NN-FW

The Bosch Rexroth Indramat RD52.2-4B-007-D-NN-FW from the RD 500 Drive Controllers series is a high-performance AC drive converter featuring a converter with a built-in brake chopper. It accepts a nominal connecting voltage of 3 x AC 380–480 V and delivers a rated power of 7.5 kW at a 4 kHz pulse frequency, with a secondary rating of 5.5 kW at 8 kHz. The unit employs a robust plug-through cooler requiring 0.03 m³/s of airflow for optimal thermal control. Housed in an IP20 protection enclosure, it is designed for seamless integration inside industrial control cabinets.

At a 4 kHz switching frequency, the RD52.2 delivers an output frequency range of 0–250 Hz, with a continuous current of 18 A and a peak current of 23 A sustained for up to 60 seconds. This configuration yields a rated output of 12 kVA and a peak power of 15 kVA under short-burst conditions. When reconfigured to 8 kHz, the drive achieves an output frequency range of 0–500 Hz, with 13 A continuous current and 17 A peak current, producing an 8.6 kVA rated output and 11 kVA peak power for 60 seconds. Its thermal performance is rated for ambient temperatures from 0 to 40 °C, with a 2.5% derating per °C between 40 and 50 °C to protect electronic components.

Efficiency is underscored by a power loss of 0.33 kW during operation and a compact size class A footprint. The drive’s input rating of 380–480 V AC supports global deployment, and its one-year warranty from Wake Industrial ensures reliability in demanding automation and motion control applications.
