RD52.1-4B-160-R-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-160-R-NN-FW is a high-performance unit in the RD 500 Drive Controllers series, designed for demanding industrial motor control applications. As an AC Drive Converter, it delivers a Rated Power of 160 kW and operates on a Nominal Connecting Voltage of 3 x AC 380-480 V, ensuring compatibility with standard three-phase supplies. Featuring a liquid cooling with internal pump mechanism, this converter maintains optimal temperature levels under continuous load, making it ideal for environments requiring sustained high-power operation.

Inside its rugged housing—measuring 1270 mm in length, 480 mm in width, and 380 mm in depth—the RD52.1-4B-160-R-NN-FW weighs 157 kg (excluding optional accessories) and handles overload conditions of 377 A per minute and 493 A per second. Heat generated during operation is efficiently dissipated by circulating coolant to the internal components. The unit integrates a 100-kg brake chopper with 144 kW braking power and 2.2 Ω resistance, enabling safe dissipation of regenerative energy. Built to IP20 standards, the converter is suitable for use with or without an encoder and supports both three-phase induction and synchronous motors. The firmware is available separately and must be procured to activate advanced control features.

Engineered for reliability, the RD52.1-4B-160-R-NN-FW meets the supplier’s 3K3 environmental grade requirements and operates safely in ambient temperatures between 0 °C and 40 °C, with humidity below 90%. Installation and commissioning should be performed by qualified specialists to guarantee peak performance and adherence to safety regulations. Backed by a one-year global warranty, this converter provides industrial users with enhanced efficiency, precise motor control, and robust protection against electrical and environmental stresses, making it an indispensable asset in modern automation systems.
