RD52.1-4B-011-L-NN-G3-T1-FW

The Bosch Rexroth Indramat RD52.1-4B-011-L-NN-G3-T1-FW from the RD 500 Drive Controllers series is a high-performance AC drive converter designed for precision control of synchronous and induction motors. It operates on a Nominal Connecting Voltage of 3 x AC 380-480 V and delivers a Rated Power of 11 kW, making it ideal for demanding industrial applications. Engineered as a Converter with a built-in brake chopper, the RD52.1 model integrates seamless torque control and rapid dynamic response. The drive’s compact footprint and robust construction ensure straightforward integration into existing automation panels.

Reliability is ensured by the drive’s forced air cooling system, which maintains optimal operating temperatures even under continuous load. A built-in mains filter minimizes anomalies on the AC supply, while integrated radio interference suppression filters and a line reactor control harmonics and protect upstream equipment. The removable user panel features a four-line graphical display for intuitive parameter setup, and commissioning can also be performed via the RDwin PC software. Short-circuit protection and peer-to-peer coupling or Synchrolink drive-to-drive communication add layers of functional safety and network flexibility.

Rated to withstand 200% overload for 0.5 seconds and 170% overload for 1 second, the RD52.1-4B-011-L-NN-G3-T1-FW excels in start-stop and cyclic duty cycles. Bosch specifies an optimal ambient temperature range of 0 to 40 °C, with permissible operation up to 50 °C under output derating. Global shipping and a one-year warranty from Wake Industrial complete the package, offering end users peace of mind and reliable service support.
