Frequency Inverter / Variable Frequency Drive — 1pc, 0.75 kW · 1.5 kW · 2.2 kW · 4 kW · 5.5 kW Key specifications: 1PH / 3PH input, 220V / 380V, output frequency 0.1–400 Hz What this product does Controls AC motor speed and torque by varying output frequency and voltage, enabling precise motor control and improved process consistency. Converts incoming single-phase or three-phase power (1PH/3PH, 220V/380V) into a variable-frequency output across 0.1–400 Hz to match application requirements. Supplied as a single unit (1pc) in the following power ratings: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW. Why customers need it (benefits) Energy efficiency: Match motor speed to load conditions to reduce power consumption compared with fixed-speed operation. Improved process control: Precise frequency control enables smoother starts/stops and consistent speed for production and processing tasks. Reduced mechanical stress: Controlled acceleration and deceleration lower wear on motors, belts, gears, and driven equipment. Versatile compatibility: Supports both single-phase and three-phase installations at common industrial voltages (220V and 380V), simplifying replacement or upgrade of existing motor drives. Performance and functional highlights Wide output frequency range (0.1–400 Hz) suits slow-speed positioning through to high-speed operation. Available in multiple power ratings to match motors from fractional to several kilowatts without over-specifying. Functions as an output converter/variable frequency drive to directly control standard AC motors. Compatibility and installation notes Choose the model with the correct power rating (0.75 kW to 5.5 kW) for your motor and load. Input can be single-phase or three-phase; ensure supply voltage matches either 220V or 380V version as required. Intended for replacing or upgrading conventional fixed-speed drives where variable speed control is needed. Practical application scenarios Pump and fan control: Use the inverter to regulate motor speed based on flow or pressure requirements, reducing energy use and preventing water hammer or mechanical shock. Conveyor and material handling: Provide smooth acceleration and deceleration for conveyors, improving product handling and reducing line jams and mechanical stress. Machine tools and mixers: Deliver precise speed control for smaller manufacturing equipment, enabling repeatable processing and better process quality. What to verify before purchase Confirm motor power and current requirements match the selected inverter rating. Verify supply voltage and phase (220V or 380V; single-phase or three-phase) match the inverter model. Confirm the required output frequency range fits the application (0.1–400 Hz). Technical summary Product type: Frequency inverter / Variable Frequency Drive (1pc) Power ratings available: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW Input: 1PH / 3PH, 220V / 380V Output frequency range: 0.1–400 Hz Use this inverter when you need reliable, energy-efficient speed and torque control for AC motors in industrial, commercial, or light manufacturing applications.
