Description

The Bosch R911200872 (RD51.1-4N-018-D-NN-FW) is a universal drive controller compatible with three-phase AC systems, specifically operating within the range of 380 to 480 Volts AC. It has an 18.5 kilowatt-rated motor output, but does not come with a brake chopper. Various optional functions such as frequency converter and stand-by power can enhance functionality as per individual requirements. The product requires separate ordering of firmware and includes a plug-through cooler. It operates effectively at a pulse of 4 kilohertz, delivering 23kVA rated output, 35 Amps of current output and an 18.5-kilowatt motor output or at 8 kilohertz providing a 20kVA rated output, 30 Amps current output, and a 15-kilowatt motor output. Its size class is 'B' and features a radio interference suppression filter to minimize power harmonics. The controller’s IP20-rated housing is not liquid-protected, hence should be used indoors, ideally within a control cabinet. Configuration can be carried out through an optional control panel or PC-based software. Skilled personnel are recommended to handle installation to avoid compromising its operation. Available for global shipping, it comes with a one year warranty from Indramat USA.
