RD52.1-4N-315-F-V1-FW

The RD52.1-4N-315-F-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers delivers a high-performance AC drive converter engineered for modern motion control applications. This compact converter accepts a Nominal Connecting Voltage of 3 x AC 380-480 V and provides a continuous Rated Power of 315 kW with high precision. Its robust design combines forced air cooling with an integrated liquid circulation circuit to maintain optimal thermal performance under load. A sleek IP20 housing and converter-only unit type ensure easy integration into standard control cabinets without added brake chopper hardware.

In operation, the drive draws a Rated Current of 540 A and supports an output frequency range from 0 to 150 Hz for fine speed regulation. It sustains a peak current of 702 A for 60 s and 918 A for 1 s to handle transient loads and torque spikes. The converter delivers up to 355 kVA apparent power while maintaining 3K3 Environmental Class compliance for ambient temperatures between 0 and +40 °C. Its thermal management strategy dissipates 11.8 kW of internal power loss through a forced air and liquid circuit, ensuring stable operation even in demanding duty cycles.

Engineers benefit from straightforward cabinet integration thanks to the converter’s compact footprint and standard protection rating. The RD52.1 series’ proven reliability and precise current control make it ideal for heavy-duty servo drives, conveyor systems, and high-inertia loads. With global shipping support and a 24 V standby option, the RD52.1-4N-315-F-V1-FW simplifies commissioning and maximizes uptime in industrial automation environments.
