RD52.1-4N-400-R-MV-FW

The RD52.1-4N-400-R-MV-FW drive converter from Bosch Rexroth Indramat in the RD 500 Drive Controllers series offers robust AC drive performance for demanding industrial environments. This fully featured AC drive is engineered to deliver precise motion control across a broad spectrum of applications, marrying high power density with compact packaging. Built with a focus on durability and efficiency, the unit features an IP20 enclosure and is intended for installation in a higher-IP-rated cabinet. All components are factory-tested to ensure ready integration and reliable startup in process, packaging, and machine tool systems.

Designed for synchronous and induction motors, this converter operates on a Nominal Connecting Voltage of 3 x AC 380-480 V and supplies up to Rated Power of 400 kW. It delivers a Rated Current of 540 A and supports an Output Frequency Range from 0 to 250 Hz, granting high-resolution speed control. The Cooling Mode uses liquid circulation via an internal pump, maintaining thermal stability under full load. The module weighs 312 kg and features an Unit Type with no built-in brake chopper for streamlined integration. An IP20 Protection Class housing protects internal electronics, while the recommended Operating Temperature range of 0 to +40 °C ensures optimal response in standard industrial climates.

Engineers benefit from the converter’s modular design, which simplifies integration into existing control architectures and reduces installation time. High-performance liquid cooling enhances reliability by preventing thermal overload during continuous operation. This compact, high-power-density drive excels in conveyor drives, chemical processing, and heavy-duty manufacturing, delivering consistent torque and speed control when uptime and precision are essential.
