RD52.1-7N-075-D-V1-FW/S122

RD52.1-7N-075-D-V1-FW/S122, Bosch Rexroth Indramat, RD 500 Drive Controllers is a robust DC supply inverter designed for precise motor control in industrial environments. This drive controller accepts a Nominal Connecting Voltage of DC 530-670 V and delivers a continuous Rated Power of 75 kW. It employs a plug-through cooler Cooling Mode to maintain optimal internal temperatures during sustained heavy operation. The compact design omits a built-in brake chopper, aligning with its classification as an Inverter without a built-in brake chopper.

Engineered for rigorous duty cycles, the RD52.1-7N-075-D-V1-FW/S122 operates at standard 50/60 Hz line frequency, ensuring broad compatibility across international power grids. The device features an ambient Operating Temperature range from 0 to +40 °C, demanding adequate air gap and control-cabinet protection. An IP20 Protection Class enclosure combined with a maximum Relative Humidity of 90 % (non-condensing) safeguards the power electronics. A dedicated 24 V standby power supply preserves critical control data during mains interruption. Installation up to 1000 m altitude is supported without de-rating.

Integration of the RD52.1-7N-075-D-V1-FW/S122 into existing automation platforms is streamlined via plug-in cooler connectivity and standard control interfaces. Its reliable thermal management and absence of moving cooling parts enhance service life and reduce maintenance intervals. Widely deployed in hoists, conveyors, machine tools, and robotics, this drive controller delivers consistent performance and high system availability in demanding industrial applications.
