Product Description

The Bosch Rexroth RD42.1-4R-084-L is a power supply module. It is capable of regenerative feedback. The supply module is designed for connection to inverters with DC connection from the REFUdrive 500 series. The power supply module is suitable for regenerating into the line supply, such as when drives are braked. The main connecting voltage for the which the RD42.1-4R-084-L is designed is three-phase 380 to 480 Volts AC. The three-phase supply is fed through a line filter and a three-phase bridge rectifier. The supply module does not include a brake chopper. The DC bus nominal power for the RD42.1-4R-084-L is 83 kilowatts. Cooling method for which the module is designed is forced air cooling. This method relies on fans or blowers for increasing the rate of air flow across the surface of the operating power supply.

A fuse rated for 200 Amps can be connected to the RD42.1-4R-084-L. The DC rated current is 160 Amps and the peak DC current for 60 seconds is 240 Amps. At 400 Volts AC input the rated output is 84 kilowatts and the peak output is 127 kilowatts. At 480 Volts AC input, the rated output is 102 kilowatts and the peak output for 60 seconds is 154 kilowatts. The line supply rated current at the rated line supply power is 150 Amps. The power factor for the line supply is approximately 1.0. The losses at rated output are 1.5 kilowatts. The cooling airflow requirement is 0.2 m³/s. The size class of the RD42.1-4R-084-L as per Bosch is F. The housing of the supply module is IP20 rated. The RD42.1-4R-084-L supply module should be installed and operated by trained personnel. This product can be shipped globally with a one year warranty period from Wake Industrial.
