RD52.1-4B-160-R-M1-FW

RD52.1-4B-160-R-M1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers. The RD52.1-4B-160-R-M1-FW AC drive converter delivers high-performance motor control in demanding industrial environments. Engineered by Bosch Rexroth Indramat, this unit features robust construction and precision firmware (sold separately) to ensure consistent operation. Its compact form and integrated brake chopper simplify cabinet design and enhance safety compliance.

Detailed specifications underline the converter’s capability: it operates from a Nominal Connecting Voltage of 3 x AC 380-480 V and provides a Rated Power of 160 kW (200 HP) with a Rated Current of 290 A. The device employs Cooling Mode via liquid cooling with internal pump to maintain stable temperatures within the Operating Temp range of 0…40 °C. With an Output Frequency above 150 Hz, it maximizes torque control at high speeds. The drive is enclosed to IP20 standards, mounts at altitudes up to 1000 m, and occupies 1270 × 480 × 380 mm while weighing 157 kg.

Integration into automation systems is seamless: the built-in brake chopper and PWM output voltage with variable frequency directly modulate three-phase induction motors without external hardware. The robust design and liquid cooling ensure high reliability under continuous heavy load. Ideal for applications from heavy material handling to process pumps, the RD52.1-4B-160-R-M1-FW delivers precise speed and torque control where performance and uptime are critical.
