RD52.1-4B-315-F-NN-FW

RD52.1-4B-315-F-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers opens a new benchmark in high-power AC drive conversion with a focus on robustness and modular serviceability. This drive converter delivers an industry-leading 315 kW Rated Power output from a Nominal Connecting Voltage of 3 x AC 380-480 V, while its integrated brake chopper simplifies dynamic braking. The chassis houses a Converter with a built-in brake chopper and advanced Filter Current Feedback to ensure smooth torque transitions and reduced harmonic distortion. Designed for demanding industrial environments, it upholds Bosch Rexroth’s reputation for precision-engineered automation solutions.

Incorporating a forced air cooling with integrated liquid circulation scheme, the RD52.1-4B-315-F-NN-FW maintains optimal junction temperatures even at full load. The unit spans 1510 x 980 x 380 mm and weighs 358 kg, balancing compact footprint with service-friendly access panels. Electrical performance is characterized by a Rated Current of 540 A, with transient endurance of 702 A for 60 seconds and 918 A for 1 second to accommodate overloads. The modular design lets technicians replace individual power modules and control boards independently, reducing mean time to repair.

Seamless integration with existing RD 500 Drive Controllers ensures consistent control architecture and diagnostics via standard interfaces. The drive’s rugged enclosure and liquid-assisted cooling deliver high reliability under continuous duty cycles, while the built-in brake chopper eliminates external hardware for energy recapture. Ideal for heavy-duty conveyors, extruders, and machine tool applications, the RD52.1-4B-315-F-NN-FW maximizes uptime and simplifies maintenance across your automation line.
