Product Description

The Bosch RD52.2-4B-018-L-NN-FW is a Rexroth RD 500 RD52 drive designed for motor control applications. The drive can be used with various Bosch induction and synchronous motors. The drive has a modular architecture that allows the system to be adapted for different applications. The RD52.2-4B-018-L-NN-FW is based on a converter with integrated brake chopper. The converter is designed for 380 to 480 Volts AC input (three-phase). The output of the drive system is 18.5 kilowatts. Additional functions are not avaible on the drive. Firmware for the RD52.2-4B-018-L-NN-FW has to be ordered separately. The performance specifications for the drive depend on the pulse frequency. The supports pulse frequencies are 4 kilohertz and 8 kilohertz. For 4 kilohertz, the rated motor output is 18.5 kilowatts, the rated current is 35 Amps and output frequency range is 0 to 250 Hertz.

For 8 kilohertz, the rated motor output is 15 kilowatts, the rated current is 30 Amps and output frequency range is 0 to 500 Hertz. The RD52.2-4B-018-L-NN-FW drive cools through forced air cooling. Bosch has recommended a minimum airflow of 0.05 cubic meters per second for adequate drive cooling. The power dissipated as heat during operation by the RD52.2-4B-018-L-NN-FW is 0.57 kilowatts at 4 kilohertz pulse frequency and 0.63 kilowatts a 8 kilohertz pulse frequency. The radio interference suppression capability rating of the RD52.2-4B-018-L-NN-FW drive is A1 according to EN 55011. The degrees of protection offered by the drive housing is IP20. Therefore the RD52.2-4B-018-L-NN-FW can only be used indoors and should be installed inside a suitable switch cabinet. The operating environment should be free of corrosive gases and vapors. Trained and qualified personnel should install and operate the drive. This product can be shipped globally with a one year warranty period from Wake Industrial.
