380V Economical VFD Variable Frequency Drive Converter Inverter Models/power options: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW Function: motor speed controller / inverter / variable frequency drive Output frequency: 0.1–400 Hz What this product does Controls the speed and torque of three‑phase motors by varying output frequency and voltage. Converts fixed 380V supply into a controlled variable frequency output for precise motor operation. Provides smooth acceleration and deceleration to reduce mechanical stress and extend motor life. Key benefits — why you need it Precise speed control: Adjust motor speed across a wide range (0.1–400 Hz) to match process requirements. Energy and process efficiency: Run motors at the optimal speed for the load instead of full speed constantly. Reduced mechanical wear: Soft start/stop behavior lowers inrush current and stress on drive components and driven equipment. Versatile power options: Choose the appropriate kW rating (0.75, 1.5, 2.2, 4, or 5.5) to match your motor and application. Compatibility and function Input supply: 380V (three‑phase) Output: Variable frequency AC suitable for standard industrial three‑phase motors within the listed power ratings. Primary function: Motor speed regulation via VFD technology to control rotational speed and torque. Performance highlights Output frequency range: 0.1–400 Hz for fine speed adjustments and wide operating envelopes. Available power ratings: 0.75 kW through 5.5 kW to fit small to moderate motor loads. Practical applications (use scenarios) Pump systems: Control pump speed to maintain flow or pressure while reducing energy consumption. Conveyor and material handling: Adjust conveyor speed for production rate changes and smoother start/stop sequences. Fan, blower, and HVAC control: Match airflow to demand, improving comfort and reducing power draw. Installation and use considerations Select the VFD power rating that matches your motor nameplate (kW) and ensure the motor is compatible with variable frequency operation. Configure output frequency limits and ramp times according to the driven equipment requirements before regular operation. Mount and wire according to local electrical codes and any enclosure/ventilation recommendations from your installer or panel designer. What it is not This listing specifies an economical 380V VFD with the listed power ratings and output frequency range. It does not include additional accessories, enclosure specifications, or protections beyond the standard inverter function unless provided separately. Choose this 380V economical VFD when you need reliable, adjustable motor speed control across a wide frequency range for industrial or commercial motor-driven equipment.
