Heavy-Duty Vector-Control VFD for Industrial Motors, Pumps & Agricultural Machinery

The AnyHertz FST-650S 5.5 kW / 7.5 HP VFD is built for heavier motors that demand strong torque, smooth control and reliable protection. It accepts single-phase or three-phase power and outputs 230V three-phase for industrial-grade performance without needing utility three-phase service.

With advanced vector algorithms, PID control, DC braking, torque boost, and configurable speed profiles, this drive is ideal for continuous-duty industrial and agricultural operations.

Key Benefits

- High torque for starting heavy loads

- Integrated autotuning for optimal motor performance

- Energy-efficient speed modulation

- Supports demanding pump and compressor applications

- Full electronic protection suite

- Excellent for industrial and agricultural installations

Ideal For

- Agricultural and irrigation pumps
