RD52.1-4N-001-L-NN-P1-NN-FW

The RD52.1-4N-001-L-NN-P1-NN-FW AC Drive Converter from Bosch Rexroth Indramat is part of the robust RD 500 Drive Controllers series. This versatile converter operates at a Nominal Connecting Voltage of 3 × AC 380–480 V and delivers a Rated Power of 1 kW. The unit is classified as a Converter without a built-in brake chopper, making it suitable for driving a wide range of synchronous and induction motors. Engineered for precision and reliability, its primary function is to regulate motor speed and torque in demanding industrial automation applications.

Featuring a forced air cooling mechanism with an integrated blower unit, the RD52.1-4N-001-L-NN-P1-NN-FW maintains stable internal temperatures even under continuous operation. Its modular design ensures installation flexibility and simplifies maintenance. The converter includes a PROFIBUS-DP interface for seamless communication with motor controllers and PLCs. A dedicated 32-bit signal processor provides high dynamic response for servo applications, enabling rapid acceleration and deceleration profiles. The absence of a built-in braking chopper underscores the necessity of matching this module with specified external brake resistors for complete system protection.

Additional features include radio interference suppression filters and line reactors to minimize harmonics fed back into the supply, ensuring compliance with electromagnetic compatibility requirements. The enclosure meets the IP20 protection rating, safeguarding internal components against foreign objects. Designed for operation in ambient temperatures from 0 °C to +40 °C with up to 85% relative humidity (non-condensing), the converter weighs approximately 15 kg and requires a minimum clearance of 100 mm above and below for adequate airflow. With global shipping and a one-year warranty provided by Wake Industrial, this compact drive converter offers enhanced durability, efficiency, and ease of integration, delivering reliable performance in industrial automation environments.
