RD52.1-4B-132-F-V1-FW

The Bosch Rexroth Indramat RD52.1-4B-132-F-V1-FW drive converter is part of the prestigious RD 500 Drive Controllers series designed to meet the rigorous demands of industrial automation. This digital drive controller operates with a nominal connecting voltage of 3 x AC 380-480 V and delivers a substantial rated power of 132 kW for high-performance motor control. Featuring forced air cooling with integrated liquid circulation, the RD52.1-4B-132-F-V1-FW ensures efficient thermal management under continuous operation. Its primary function is to convert AC supply voltage into precise motor drive signals, enabling smooth acceleration, deceleration, and torque control in complex drive systems.

Equipped with a built-in brake chopper, the converter provides 40 kW continuous power and 100 kW peak power handling for dynamic braking applications. The input rating of 380 to 480 V AC supports global voltage standards, while an additional 24 V standby power feature allows parameterization and data handling even when main line voltage is absent. A floating 24 V DC control supply at terminal X83 prevents ground loops and safeguards control electronics. Engineers can read, write, and update parameter sets without line supply, streamlining commissioning and maintenance tasks.

Additional features underscore the RD52.1-4B-132-F-V1-FW’s reliability and compliance with industrial environments. Weighing 180 kilograms, the unit dissipates 5.2 kW of heat and operates safely in ambient temperatures between 0 and 40 °C, with a derating rate of 2.5% per °C from 40 to 50 °C. Installation above 50 °C or at elevations beyond 1,000 meters is not permitted. The enclosure provides IP20 protection and meets 3K3 environmental class per DIN IEC 721-3-3, with relative humidity up to 90%. Only qualified personnel should install the drive and accessories. Shipped globally with a one-year warranty, this converter delivers robust performance, enhanced efficiency, and long-term durability for demanding industrial applications.
