RD52.1-4B-001-D-NN-FW

The RD52.1-4B-001-D-NN-FW from Bosch Rexroth Indramat in the RD 500 Drive Controllers family delivers precise AC drive conversion with a nominal connecting voltage of 3 x AC 380-480 V and a continuous power rating of 1 kW. Housed in an IP20-rated enclosure, it requires cabinet mounting and integrates a plug-through cooler mechanism for effective thermal management. Weighing approximately 15 kg, this converter features a built-in brake chopper and supports both induction and synchronous motors. Its efficiency ranges between 0.97 and 0.98, ensuring minimal energy loss during operation.

Optimized for industrial installations, the unit type combines a converter and brake chopper in a single compact module. The device operates reliably within an ambient temperature window of 0 to 40 °C and demands professional installation to maintain warranty compliance. Under rated conditions, it delivers up to 1.5 kW peak output and handles a maximum current draw of 6.8 A/s during startup. For extended load cycles, it sustains 5.2 A for sixty seconds and tolerates 8 A for fifty-five milliseconds without derating.

Maintenance and integration are simplified through standardized connection points and adherence to factory-approved accessories. The converter’s thermal design, featuring the plug-through cooler, prevents thermal runaway and extends service life. When paired with Bosch Rexroth control systems, this drive converter accelerates commissioning and guarantees consistent motion control performance throughout demanding industrial applications.
