Product Description

Industrial induction and synchronous motors require state-of-the-art drives and controllers for them to be precisely controlled in industrial applications. Rexroth frequency converters and inverters are specially designed to provide specific solutions. To prepare the inverters and converters to handle a wide range of requirements, they have a modular hardware and software design. By featuring freely-switchable function blocks to address simple programmable logic controllers’ requirements, these drives eliminate the need for expensive control hardware. Rexroth frequency converters have a superior control performance. For example, some converters employ flux vector control which eliminates the need for a feedback device even when interfaced with synchronous motors.

The Bosch Rexroth RD51.2-4B-003-L-NN-FW is a frequency converter with a power range of between 3 Kilowatts and 18.5 Kilowatts. The converter supports forced air cooling which is more efficient that room cooling allowing the RD51.2-4B-003-L-NN-FW to strictly operate within its rated operating surrounding temperature. For its operating voltage, the converter is designed to attain optimal performance with a voltage ranging from 380 Volts AC and 480 Volts AC supplied from a 3-phase power source. The efficiency of the RD51.2-4B-003-L-NN-FW on the industrial floor is enhanced by a built-in braking chopper. The chopper functions by controlling the voltage especially when the load delivers energy back into the intermediate circuit.

Note that the braking chopper is extremely important when the RD51.2-4B-003-L-NN-FW is operated in an industrial environment where braking is regular. Braking operation must be conducted even during main power loss or when the overall amount of braking power is high. The RD51.2-4B-003-L-NN-FW has an overload capacity of 130 percent for 60 seconds, 170 percent for 1.0 seconds, and 200 percent for 0.5 seconds (up to 110 Kilowatts). With an IP 20 ingress protection rating, the converter is meant for environments with small solid objects and away from liquids.
