Product Description

The Bosch RD52.1-4B-037-L-NN-NN-NN-FW is a RD series universal drive system. The RD series drives connect to 3-phase AC input and include AC drive converters, inverters, rectifiers and supply modules. Power section on the RD drives is designed for cooling at the rear. RD drives are commissioned with prompts using the operator panel with graphical display or through a PC running the RDwin software. Technical characteristics of RD series drives include AC or DC supply, removable user panel with parameter copy function, peer to peer coupling or Synchrolink for communication between drives and support for multiple motor control interfaces including SERCOS and Profibus. The RD52.1-4B-037-L-NN-NN-NN-FW contains ESD sensitive parts. Therefore, standard ESD precautions, such as use of grounded wrist straps and use of conductive packaging for storage of components, should be followed to prevent equipment damage.

As per the type code for the drive, the field oriented regulation for the RD52.1-4B-037-L-NN-NN-NN-FW is 52. The nominal connection voltage is 380 to 480 Volts AC (three-phase) with 10% allowed variance. The drive comes with integrated converter with built in brake chopper. The converter on the drive equipped is with AC mains filter. Performance data for the chopper includes 23 kilowatts continuous power, peak power of 93 kilowatts for 1 second and maximum resistance of 7 ohms. Rated power output of the drive is 37 kilowatts. At 4 kilohertz pulse frequency the rated output current for the RD52.1-4B-037-L-NN-NN-NN-FW is 68 Amps and the rated output power is 45 kVA. The drive is cooled through forced air cooling and requires 0.2 m³ per second air flow for proper cooling. During operation the RD52.1-4B-037-L-NN-NN-NN-FW dissipates 1 kilowatt as heat. Weight of the drive is 36 kilograms. This product can be shipped globally with a one year warranty period from Wake Industrial.
