RD52.1-4B-022-L-LV-FW

RD52.1-4B-022-L-LV-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers leads the REFUdrive RD50 family with a robust, modular converter architecture. It delivers a Rated Power of 22 kW from a Nominal Connecting Voltage of 3 x AC 380-480 V, and integrates a Unit Type: Converter with a built-in brake chopper. Forced air cooling ensures consistent thermal management under sustained loads, while the compact footprint suits dense control cabinets. A one-year warranty backs the design, reflecting rigorous quality assurance.

Powered by a high-performance chopper stage, this drive accepts an Output Frequency range of 0–250 Hz and features an IP20 degree of protection without connection terminals, per EN 60529. A Line code of 1 simplifies system configuration, and a Size class C chassis supports installation at up to 1,000 m elevation. The unit’s forced air cooling maintains operation up to +50 °C ambient, and its built-in brake chopper reclaims energy during deceleration. Each controller must be mounted vertically inside a dry, clean cabinet and remain permanently earth-grounded to meet EMC requirements.

Engineers value the RD52.1-4B-022-L-LV-FW for seamless integration into automated lines, where its modular form factor and vertical-mount design streamline installation. The drive’s chopper-enabled braking function and precise frequency control enhance responsiveness in drive trains, conveyors, and centrifugal load applications. Rugged IP20 protection and stringent storage and handling guidelines ensure reliability in industrial environments.
