The industrially designed R911200987 (RD51.2-4B-005-L-A1-FW) is a versatile drive controller part of the RD51 series from Bosch Rexroth. This controller can be used with both synchronous and induction motors, which are also known as asynchronous motors. It operates off a converter rated for 380 to 480 Volts AC (three-phase). Additionally, the controller outputs a power rating of 5.5 kilowatts at 380 to 480 Volts AC input and 2.8 kilowatts at 200 to 230 Volts AC. This high-powered controller is excellent for use in varied sectors, including chemical and process technology, machine tools and packing machines. The R911200987 (RD51.2-4B-005-L-A1-FW) requires forced-air cooling and can function optimally at an ambient temperature of 0 to 40 degrees Celsius. To keep itself protected from dust and moisture, this IP20 rated controller needs cabinet mounting. The brake chopper in the converter has a continuous power rating of 2.8 kilowatts and a peak power of 18 kilowatts. With an approximate shipping weight of 6.5 kilograms, it comes with a one-year warranty from Indramat USA.
