Product Description

The RD52.1-4B-007-L-V1-FW is a Bosch Rexroth RD52 series drive controller. The RD52 series supports multiple cooling methods include forced air cooling, plug through cooler and natural convection. The RD52.1-4B-007-L-V1-FW is designed for forced air cooling. The permitted ambient temperature range for drive operation is 0 to 40 degrees Celsius. The drive output derates at a rate of 2.5% per K for temperatures between 40 and 50 degrees Celsius. The minimum cooling air requirement is 0.03 cubic meters per second. The drive power loss is 0.33 kilowatts. The RD52.1-4B-007-L-V1-FW is designed for mounting at the rear. It can be mounted with the heat sink inside or outside the enclosure. The drive includes an integrated radio interference suppression filter and complies with level A1 of EN 55011 for noise immunity and interference suppression.

The drive converter is rated for 380 to 480 Volts AC input. The converter features a brake chopper. Brake choppers are used to control voltage when the load feeds energy back to the intermediate circuit. The continuous power rating of the brake chopper is 3.8 kilowatts. The continuous power rating of the brake chopper is 18 kilowatts. The rated output of the RD52.1-4B-007-L-V1-FW at 4 kilohertz pulse is 7.5 kilowatts, the rated current output is 18 Amps, and the peak current output is 31 Amps for 0.5 seconds. The rated output of the RD52.1-4B-007-L-V1-FW at 8 kilohertz pulse is 5.5 kilowatts, the rated current output is 13 Amps, and the peak current output is 26 Amps for 0.5 seconds. An additional function that is supported by the RD52.1-4B-007-L-V1-FW is 24 Volts stand by power. The firmware for the RD52.1-4B-007-L-V1-FW drive has to be ordered separately. This product can be shipped globally with a one year warranty period from Wake Industrial.
