Slanvert Hope530 55KW 380V 3PH

SLANVERT Hope530G55T4 – 55kW (75HP) 380V Three-Phase Vector Control VFD

The Hope530G55T4 is a 55kW / 75HP variable frequency drive (VFD) from the SLANVERT Hope530 series, engineered for precise three-phase induction motor speed control at 380V–480V, 50/60Hz. Built on a rotor-flux-oriented sensorless vector control platform, it delivers high starting torque, stable low-speed running and energy-efficient operation for demanding industrial loads — making it a reliable variable speed drive (VSD) upgrade for pumps, fans, conveyors, compressors, extruders, mixers, cranes and general process machinery.
