The R911200202 (RD51.1-4N-011-L-NN-FW) is a modular three-phase AC drive converter from the Indramat Refu RD 500 series, engineered for use with both synchronous and induction motors. This unit is suitable for applications not requiring servo performance, such as gears, centrifuges, and pumps. It controls output using voltage frequency (U/f) regulation and supports pulse modulation frequencies of 4, 8, or 12 kHz. The converter features a nominal power rating of 11 kW and is designed for operation on 3 x AC 380–480 V supply with ±10% tolerance. Cooling is achieved via forced air, and the enclosure provides IP20 ingress protection. Additional technical characteristics include the absence of a brake chopper and compatibility with the REFUwin software tool. A removable user panel enables parameter transfer between drives.
