The Bosch Rexroth R911200730 (RD51.1-4N-001-L-DF-FW) is a voltage frequency control (VFC) drive converter designed for operation with three-phase AC input voltage ranging from 380 to 480 V AC (±10%). It is engineered to operate at a maximum altitude of 1000 meters above sea level and delivers a rated output power of 1 kW (2 HP) at 460 V. The unit requires installation within a control cabinet and utilizes forced air cooling to maintain operational temperatures, with airflow unobstructed and free from hazardous or conductive gases. The R911200730 is compatible with add-on modules, such as the RZC01.1-XT, and supports feedback of current filter (U6, V6, W6). The converter does not include a built-in brake chopper, and it does not come with firmware pre-installed, requiring separate acquisition. Operation in environments with relative humidity above 90% is not recommended.
