Product: 1pc Inverter / Frequency Inverter / Variable Frequency Drive (VFD) Models and power options: 0.75KW, 1.5KW, 2.2KW, 4KW, 5.5KW Compatibility: 1PH / 3PH, 220V / 380V Output frequency range: 0.1–400 Hz Key benefits Precise motor speed control: Adjusts motor frequency from 0.1 to 400 Hz to match process requirements, reduce energy waste, and improve product consistency. Broad compatibility: Works with single-phase and three-phase installations at 220V or 380V, covering common residential, commercial, and industrial power supplies. Flexible power options: Available in five power ratings (0.75, 1.5, 2.2, 4, 5.5 kW) to suit small to mid-size motors and varied application needs. Simple single-unit supply: Supplied as 1pc inverter for direct replacement or integration into control panels. What it does and how it solves problems Converts incoming AC power to a controllable output frequency and voltage, enabling smooth acceleration/deceleration and reducing mechanical stress on motors and driven equipment. Improves process control and saves energy by allowing motors to run only as fast as required rather than at full speed continuously. Protects equipment by enabling controlled starts/stops, lowering inrush currents, and reducing wear on belts, gears, and bearings. Important attributes Function: Variable frequency drive / output converter for AC motors. Compatibility: Supports both 1PH and 3PH systems and standard 220V or 380V supplies. Performance: Wide output frequency range of 0.1–400 Hz for precise speed control across many applications. Form factor & installation: Supplied as a single compact unit; suitable for panel or cabinet mounting. Refer to the product datasheet for exact dimensions and enclosure material. Reliability: Designed to provide consistent frequency conversion and motor control in routine industrial and commercial use. Typical applications (practical use scenarios) Pumps and fans: Smooth speed control for flow regulation and reduced energy consumption in HVAC, water treatment, or irrigation systems. Conveyors and material handling: Precise speed adjustment and soft start/stop to protect product and reduce mechanical shock on conveyors or packaging lines. Small machine tools and mixing equipment: Accurate speed control for process consistency in light manufacturing, woodworking, or food processing. Ordering and installation notes Choose the inverter power rating that matches the motor nameplate (0.75, 1.5, 2.2, 4, or 5.5 kW). Verify supply type (single-phase or three-phase) and voltage (220V or 380V) before installation. Consult the technical datasheet and wiring diagram for mounting requirements, terminal connections, and any required protective devices.
