The Bosch Rexroth R911200306 (RD51.1-4B-015-L-NN-FW) is an advanced drive converter designed for various high-tech sectors, known for its quality and value. With its compact dimensions (500mm tall, 135mm wide, and 320mm deep) and 18kg weight, it fits easily into most industrial settings. This model operates on a maximum of 39 amps for 60 seconds, accelerated to 51 amps for a one-second burst. It pairs a robust RD52.1 drive converter, offering 15 kW of power at a 30 Ampere rated current, with a brake chopper that delivers up to 0.2 kW with a 17.5-ohm resistance. The R911200306 (RD51.1-4B-015-L-NN-FW) features an IP20 protection class and requires a closed cabinet set-up packed with noise reduction measures. Its slick modular concept allows individual component replacement for system maintenance, while a separate blower unit provides cooling for sustained high power. Firmware for the device must be acquired separately, and specialist training is advised for operation.
