The Rexroth Indramat R911203237 (RD51.1-4B-200-F-V1-FW) is a high-performance drive converter model equipped with innovative features. Specifically crafted to control the speed of electric motors, it changes the frequency of the three-phase input voltage to which it's directly connected (3 x AC 380-480 V with a ±10% tolerance). The robust drive converter can run a 200kW motor with a 50/60 Hz frequency and houses built-in brake choppers for reliable overvoltage protection. Cooling is handled through forced air cooling with integrated liquid circulation, while a 24 V standby power supply ensures uninterrupted operation. Suitable for use with RD500 specified accessories and elements, it finds application across chemical and process technology, machine tools, conveyance systems, and more. It possesses an ambient operating temperature range of 0 to +40°C, and IP 20 protection, requiring installation in an IP 54 class control cabinet. This product comes with a one-year warranty from Indramat USA.
