R911200403
Produced by Bosch Rexroth Indramat, the R911200403 (RD52.1-4B-004-L-V1-FW) is a 4 kilowatt drive controller, specifically engineered for three-phase AC mains functioning at 380 to 480 Volts AC. The device also works with three-phase AC mains operating at 200 to 230 volts AC, though output derates by 50% in such instances. Built on a converter with a built-in brake chopper, the drive can function at multiple pulse frequencies, including 4 kilohertz, 8 kilohertz, and 12 kilohertz with forced air cooling for heat management during regular operation.
The R911200403 (RD52.1-4B-004-L-V1-FW)’s functionality depends on ambient conditions, ideally 0 to 40 degrees Celsius, with an altitude range of 0 to 1,000 meters, and relative humidity up to 90% (non-condensing). The environment surrounding the drive should be free from corrosive gases and dust, with an air filter being recommended to manage dusty conditions. The IP20-rated casing of the controller does not offer protection from dust or moisture. Limitations include a maximum installation site temperature of 55 degrees Celsius and maximum elevation of 2,000 meters. When not in use, the controller should be stored in a clean, dry area where the ambient temperature lies between -25 to 70 degrees Celsius. This device supports 24 Volt standby power and measures 440 millimeters in height and 90 millimeters in width.
