RD52.1-4B-075-D-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-075-D-NN-FW drive controller belongs to the prestigious RD 500 Drive Controllers series. Designed as an AC drive converter, it operates on a nominal connecting voltage of 3 x AC 380-480 V and delivers a rated power of 75 kW. Featuring a plug-through cooler, this modular controller handles demanding motion control tasks in industrial automation. Its primary function is to regulate motor speed and torque precisely, making it ideal for dynamic drive applications where reliability and performance are paramount.

The RD52.1-4B-075-D-NN-FW is equipped with a built-in brake chopper to safely dissipate regenerative energy and protect connected equipment. The converter supports three-phase AC input voltages from 380 to 480 Volts AC, ensuring compatibility with common plant power supplies. A removable user panel allows quick parameter copying and facilitates on-site configuration, while the converter’s design supports seamless integration with the RDwin software for advanced programming. The controller’s unit type combines converter functionality with an integrated brake chopper, setting it apart in applications requiring both drive control and braking management in a single module.

Built for durability in controlled environments, the RD52.1-4B-075-D-NN-FW is rated IP20 and requires dust-free air without aggressive or electrically conducting gases. It operates optimally at ambient temperatures between 0 and 40 °C (derated output up to 50 °C) and relative humidity below 90% (no condensation). These features ensure long-term reliability and thermal efficiency under industrial conditions. By combining high overload capability, modular cooling, and integrated braking, this drive controller enhances system efficiency, reduces installation complexity, and delivers robust performance for a wide range of industrial motor control and automation applications.
