This Variable Frequency Drive (VFD) is a general-purpose three-phase motor control device. It achieves smooth speed regulation, soft start/stop, and energy-saving control for AC motors by varying the frequency and voltage of the power supply. It is primarily used in driving motors for industrial equipment such as fans, pumps, compressors, conveyors, and machine tools.

Precise Speed Control: Enables wide-range stepless speed regulation of three-phase induction motors to meet various process requirements.

Soft Start/Stop: Reduces inrush current during motor startup, minimizing stress on the power grid and mechanical transmission parts, thereby extending equipment service life.

Energy-Saving Potential: For variable torque loads like fans and pumps, adjusting motor speed instead of using valves/dampers can lead to significant energy savings.

Basic Protection Functions: Provides protection against overcurrent, overvoltage, undervoltage, overheating, short circuits, and motor overload.

Multiple Control Modes: Supports control via keypad potentiometer, external terminals, and RS-485 communication (confirm model support).

Stable Operation: Designed for reliable operation in standard industrial environments.

Airflow regulation for industrial fans, blowers, and cooling fans.

Flow and pressure control for various pumps and liquid circulation systems.

Speed adjustment for conveyors and production lines.

Spindle speed control for basic machine tools (e.g., grinders, drill presses).

Input Power: 3-Phase, 380V ±15%, 50/60Hz

Output: 3-Phase, 0~Input Voltage, 0~400Hz
