RD52.1-4B-200-F-NN-NN-NN-FW

RD52.1-4B-200-F-NN-NN-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers series presents a high-performance AC drive converter engineered for demanding industrial environments. It operates on a Nominal Connecting Voltage of 3 x AC 380-480 V and delivers a Rated Power of 200 kW. The unit features forced air cooling with integrated liquid circulation and an integrated Converter with a built-in brake chopper plus an on-board Mains Filter. Rugged construction and factory acceptance testing ensure each module meets stringent safety and reliability standards.

This drive supports dual pulse frequencies: at 4 kHz pulse frequency it provides a continuous 200 kW output power and at 8 kHz pulse frequency it delivers 160 kW. When fed from a 500 V AC supply, the Rated Current reaches 280 A at 4 kHz and 240 A at 8 kHz. Output frequency spans 0–150 Hz at 4 kHz and 0–250 Hz at 8 kHz, while Power Loss is 7.7 kW at 4 kHz and 6.5 kW at 8 kHz. The drive requires a Cooling Airflow of 0.6 m³/s, carries a Protection Class of IP20, and operates over an ambient range of 0…40 °C. Weighing 180 kg, it also features a 40 kW continuous chopper rating for dynamic braking.

Integration into automated systems is seamless, thanks to the compact footprint of the Unit Type and built-in power electronics. The combined brake chopper and mains filter reduce external components, lowering overall footprint and installation complexity. Bosch Rexroth Indramat’s rigorous quality control and robust IP20 housing deliver reliable performance in machine tools, chemical processing, packaging, and foodstuff equipment. This drive ensures long-term uptime and simplified maintenance across diverse industrial applications.
