RD52.1-4B-005-L-NN-NN-NN-FW

RD52.1-4B-005-L-NN-NN-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers opens a new chapter in compact AC drive technology. This industrial-grade converter accepts a Nominal Connecting Voltage of 3 x AC 380-480 V and delivers a continuous Rated Power of 5.5 kW directly to synchronous or induction motors. Equipped with forced air cooling, the RD52.1-4B-005-L-NN-NN-NN-FW maintains thermal stability under heavy load and extended runtime. A built-in brake chopper enhances dynamic braking performance without requiring separate hardware.

Incorporating robust hardware, the controller supports a Rated Current of 13 A and features an IP20 Protection Category enclosure rated to 3K3 Environmental Class standards. The unit’s Converter with a built-in brake chopper topology ensures seamless energy recovery during deceleration. At just 5.5 kg, the compact housing allows straightforward DIN-rail or panel mounting, while the embedded temperature sensor guards against overheating. The controller’s maximum motor winding Resistance of 60 Ω accommodates a wide variety of motor designs. A standard 1-year Warranty Period underpins the product’s dependability in global operations.

Engineered for rapid integration, the RD52.1-4B-005-L-NN-NN-NN-FW plugs into existing REFUdrive RD50 architectures via plug-and-play connectors. Its precise current and voltage regulation delivers consistent torque control, boosting production repeatability. The rugged forced-air design and IP20-rated casing guarantee reliable performance in demanding industrial environments, making it ideal for automated assembly lines, conveyor systems, and packaging machinery.
