Product Description

The Bosch Rexroth RD52.1-4N-022-L-V1-FW is a RD52 series universal AC drive. It is based on a converter that does not include a brake chopper. The input rating is 380 to 480 Volts AC (three-phase). The rated output of the drive is 22 kilowatts. The rated output is available at the drive output when ambient conditions match those that are specified by Bosch. The specified ambient conditions include 0 to 40 degrees Celsius temperature and relative humidity of less than 90%. The air in the operating environment should be dust free. Dust-laden air must be filtered (3K3 according to DIN IEC 721-3-3). The air in the operating environment should not contain electrically aggressive or corrosive gases or vapors. The RD52.1-4N-022-L-V1-FW dissipates heat during operation and should be separated from other heat generating devices.

The cooling method for which the RD52.1-4N-022-L-V1-FW is designed is forced air cooling.
