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

The Bosch Rexroth Indramat RD52.1-4B-160-F-NN-FW unit is a high-performance member of the RD 500 Drive Controllers series designed for precise AC motor control in demanding industrial environments. It operates on a Nominal Connecting Voltage of 3 x AC 380-480 V and delivers a Rated Power of 160 kW through its built-in brake chopper. The device’s primary function is to regulate motor speed and torque by converting incoming three-phase AC voltage into a controlled output, ensuring smooth acceleration, deceleration, and energy recovery under variable load conditions.

Featuring a forced air cooling with integrated liquid circulation system, the RD52.1-4B-160-F-NN-FW maintains optimal operating temperatures even under continuous heavy use. The converter supports a peak current of 377 A for one minute and a continuous Rated Current of 290 A, making it suitable for applications with high inertia or frequent starts and stops. Its brake chopper manages regenerative energy by feeding excess voltage back into the circuitry, reducing heat buildup and enhancing overall system efficiency. With dimensions of 1510 mm (H) × 480 mm (W) × 380 mm (D) and a mass of 180 kg, the unit is engineered for stability and ruggedness. The modular design requires separate firmware purchase, allowing tailored feature sets without unnecessary overhead.

The RD52.1-4B-160-F-NN-FW offers broad compatibility through shielded cable requirements for incremental encoder connections, ensuring reliable signal integrity in electrically noisy environments. Rated for operation up to 1000 meters above sea level and certified to IP20 standard, it resists dust and small particulates for long-term durability. Its forced air and liquid cooling combination optimizes energy consumption and reduces maintenance intervals compared to traditional air-only systems. Backed by a one-year warranty, this drive converter provides a cost-effective solution for integrators and OEMs seeking a versatile, efficient, and robust platform for automated production lines, conveyors, and heavy-duty servo applications.
