Product Description

The RD51.2-4B-005-L-A1-FW is RD51 series universal drive controller. Bosch Rexroth has designed the controller for use with induction motors and synchronous motors. A synchronous motor is one in which the rotation of the shaft is synchronized with the frequency of the AC supply. An induction motor is one in which the electric current needed for rotor torque is obtained by electromagnetic induction. Induction motors are also known as asynchronous motors. The RD51.2-4B-005-L-A1-FW is based on a converter with brake chopper. The converter is rated for 380 to 480 Volts AC (three-phase). The output power rating of the RD51.2-4B-005-L-A1-FW is 5.5 kilowatts at 380 to 480 Volts AC input and 2.8 kilowatts at 200 to 230 Volts AC. Typical applications for which the RD51.2-4B-005-L-A1-FW controller is used include chemical and process technology, machine tools, handling systems and packing machines.

The RD51.2-4B-005-L-A1-FW controller supports three additional function that are stand-by power, filter current feedback and starting lock-out. The RD51.2-4B-005-L-A1-FW cools through forced air cooling. This means that a fan or blower is needed for forcing air across the heated body of the operating controller. The minimum airflow rate specified by Bosch is 0.03 cubic meters per second. At lower airflow rates, the controller will heat up and could suffer damage. The ambient temperature recommended for optimal controller operation is 0 to 40 degrees Celsius. Housing of the RD51.2-4B-005-L-A1-FW is IP20 rated. This indicates that the controller requires cabinet mounting for complete protection from dust and moisture. The brake chopper on the converter has continuous power rating of 2.8 kilowatts and peak power rating of 18 kilowatts. The approximate shipping weight of the drive controller is 6.5 kilograms. This product can be shipped globally with a one year warranty period from Wake Industrial.
