Compact Vector-Control Variable Frequency Drive for Pumps, Fans & Light Industrial Machinery
The AnyHertz FST-650S 0.75 kW / 1 HP VFD is a compact, high-performance inverter designed for precise motor control, energy efficiency, and superior protection. Powered from either 230V single-phase or 230V three-phase input, it generates a stable 230V three-phase output, allowing users to operate industrial motors in workshops, garages, agricultural sites, or any location lacking true three-phase service.
With full V/F control, Sensorless Vector Control (SVC), torque boost, soft-start, PID regulation, and advanced motor autotuning, this drive delivers exceptional versatility and performance. Ideal for pumps, fans, metalworking tools, and small industrial automation systems.
