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
- 7.5 HP compressors
- Industrial fans
