✅ FAQs – Three-Phase Variable Frequency Drive (VFD)
Q1: What is a three-phase Variable Frequency Drive (VFD)?
A three-phase VFD (also known as an AC drive or industrial inverter) converts fixed-frequency three-phase AC input (e.g., 380V/415V/480V, 50/60Hz) into variable voltage and frequency output to precisely control the speed and torque of three-phase induction motors—essential for pumps, fans, conveyors, compressors, and other heavy-duty industrial machinery.

Q2: How does a three-phase VFD differ from a single-phase input model?
Unlike single-phase VFDs (limited to ≤5kW), three-phase VFDs handle higher power (typically 0.75kW to over 1000kW), deliver smoother motor operation with lower harmonic distortion, and support true three-phase power input—enabling superior efficiency, overload capacity (up to 150% for 60 seconds), and reliability in continuous industrial applications.

Q3: Can this three-phase VFD be used for water pumps or HVAC fans?
Yes. Our three-phase pump and fan inverters feature built-in PID control, constant pressure mode, and energy-saving V/F curves—optimized for centrifugal loads like booster pumps, cooling towers, and AHUs. They reduce energy consumption by up to 40% while maintaining stable system pressure or airflow.

Q5: Can it operate reliably in harsh industrial environments (e.g., mining, steel plants)?
Yes. Designed for tough conditions, our industrial three-phase VFDs feature conformal-coated PCBs, sealed heat dissipation channels, and IP20 (or optional IP54/IP65) protection. They operate stably in ambient temperatures from -10°C to +50°C and resist dust, moisture, and electrical noise—common in cement, metallurgy, and chemical facilities.
