RR52.1-7N-015-P-V1-FW

The Bosch Rexroth Indramat RR52.1-7N-015-P-V1-FW from the RD 500 Drive Controllers series is a high-performance DC supply inverter engineered for demanding industrial and textile applications. This Inverter without a built-in brake chopper module delivers a continuous Motor Output of 11 kW and supports an Output Frequency range of 0–500 Hz for precise speed control. Designed for a DC 650 V line supply with ±10% tolerance, the unit operates at a rated current of 27 A while sustaining peak currents of 39 A (60 s) , 51 A (1 s), and 60 A (0.5 s). With an integrated heat conducting plate as its primary cooling mode and an IP20 protection rating, the RR52.1-7N-015-P-V1-FW ensures reliable thermal management and robust electrical safety.

Installation flexibility is achieved through a compact design that requires filtered cabinet air supply and adequate spacing for optimal airflow. The device meets the stringent 3K3 environmental class (DIN IEC 721-3-3) standards, allowing operation in ambient temperatures from 0 °C to +45 °C and survival in short-term peaks up to +55 °C. Its inverter topology, absent a brake chopper, reduces component count and simplifies maintenance. Front-access plug-in terminals and standardized mounting provisions accelerate field replacement and minimize downtime.

Throughout its lifecycle, the RR52.1-7N-015-P-V1-FW maintains performance stability via its heat conducting plate cooling and precise current handling. Whether integrated into standalone drives or multi-module arrays, this Bosch Rexroth Indramat controller delivers cost-effective, high-reliability operation. Its combination of 11 kW output, 0–500 Hz frequency range, and robust protection class makes it an ideal choice for textile machines, automation lines, and OEM systems demanding consistent dynamic response and long-term durability.
