Economical VFD Variable Frequency Drive Converter Inverter (1 pc) 220V / 380V — Available power ratings: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW Function: Motor speed controller / variable frequency drive High-concern chemicals: None Key benefits Precise motor speed control: Adjust motor frequency and speed to match process requirements for better product quality and reduced scrap. Energy and cost savings: Run motors at the optimal speed instead of full power, reducing energy use in many applications. Smoother starts and stops: Soft-start and controlled acceleration reduce mechanical shock, lowering maintenance needs and extending motor and driven-equipment life. Simple matching to motors: Multiple power options (0.75/1.5/2.2/4/5.5 kW) and 220V/380V compatibility make it easy to choose the correct unit for existing motors. Safe for workplace and environment: No high-concern chemicals present in the product. Main features and attributes Function: Variable Frequency Drive (VFD) for precise control of AC motor speed and torque by changing supply frequency. Voltage compatibility: Designed to operate on standard 220V or 380V supplies (select appropriate voltage for your installation). Power ratings: Choose from 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, or 5.5 kW to match motor size and load requirements. Performance: Provides adjustable frequency and speed control to stabilize processes, reduce inrush current, and improve motor protection. Safety and compliance: Contains no high-concern chemicals; follow local electrical codes and installation guidelines. Practical applications / use scenarios Pump and fan control: Regulate flow and pressure by adjusting motor speed, improving efficiency in water treatment, irrigation, or HVAC systems. Conveyor and material handling: Precisely control conveyor speed for synchronization between production stages or to reduce product damage during handling. Small machinery and machine tools: Match motor speed to cutting, mixing, or forming processes to improve finish quality and reduce cycle time. Installation and selection tips Match the VFD power rating to the motor nameplate kW rating and voltage (220V or 380V) before installation. Verify motor compatibility and wiring requirements with a qualified electrician or installer. Use appropriate thermal protection and grounding as required by the application and local regulations.
