RD52.1-4B-030-L-NN-NN-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-030-L-NN-NN-NN-FW from the RD 500 Drive Controllers series is a high-performance Converter with a built-in brake chopper engineered for demanding industrial applications. This unit type supports a nominal connecting voltage of 3 x AC 380-480 V with a tolerance of b110% and delivers a continuous rated power of 30 kW. Equipped with forced air cooling, the controller maintains optimal thermal stability under sustained loads. A robust built-in chopper provides continuous braking power of 19 kW to protect both motor and drive during dynamic deceleration.

Reliability and safety are ensured through a design code of 2 and compliance with EN 50082-2 noise immunity standards. The controller features a leakage current specification of >3.5 mA and is rated for operation in dust-free environments, with filtered intake air prolonging component life. An integrated type plate details input/output voltage, current ratings, and operating frequencies for rapid verification during installation. The unit’s modular software and hardware design simplifies firmware updates, parameter adjustments, and field servicing.

Designed for control cabinet mounting in environments from 0 b0C to 40 b0C, the RD52.1-4B-030-L-NN-NN-NN-FW benefits from a compact size class C footprint and may be shipped in custom military-grade foam packaging. Backed by a one-year warranty, this vector control drive optimises motor performance in asynchronous and synchronous systems while minimising downtime and maintenance overhead.
