Frequency Inverter / Variable Frequency Drive (VFD) Models and power options: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW Phase and voltage compatibility: 1PH / 3PH, 220V / 380V Output frequency range: 0.1 – 400 Hz Key benefits Precise motor speed control: Adjust motor RPM smoothly across a wide range (0.1–400 Hz) to match process demands and improve product quality. Energy and process efficiency: Run motors at the required speed rather than full speed, reducing energy use and mechanical wear. Flexible installation: Available in multiple power ratings and supports both single-phase and three-phase systems at 220V or 380V for broad compatibility with common industrial and commercial setups. Simple system integration: Functions as a direct replacement or upgrade for fixed-speed drives to add variable speed capability without major changes to existing equipment. What it does (core functions) Converts incoming AC power to a controlled, variable-frequency output to regulate motor speed. Acts as an output converter that enables adjustable acceleration, deceleration and steady-state speed control for AC motors. Provides stable frequency output across 0.1–400 Hz to support low-speed torque and high-speed operation. Important attributes Power range: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW to match a wide range of motor sizes. Phase/Voltage: Supports 1PH and 3PH configurations at 220V or 380V for compatibility with common electrical supplies. Performance: Wide frequency span (0.1–400 Hz) enables precise control from near-zero speed to high-speed operation. Functionality: Designed as a frequency inverter / variable frequency drive / output converter for motor control applications. Practical use scenarios Pump and fan control: Regulate flow and pressure by adjusting motor speed to maintain setpoints, reduce energy consumption and prevent water hammer or overspeed conditions. Conveyor and machine feed drives: Provide smooth acceleration/deceleration and accurate speed matching for production lines, reducing mechanical stress and improving throughput consistency. Workshop machinery and small production equipment: Add speed control to milling, cutting, mixing, or other motor-driven equipment for better process control and reduced tool wear. Why customers choose this inverter Match to application: Multiple power options and phase/voltage support make it straightforward to select a unit that fits the motor and electrical supply. Wider frequency range: 0.1–400 Hz gives more control flexibility than basic drives, useful for demanding speed ranges. Direct function match: Acts as a dedicated frequency converter/variable frequency drive to solve common problems like overspeed, inefficient operation, and lack of precise speed control. Ordering and compatibility notes Choose the kW rating that matches or slightly exceeds the motor nameplate rating. Confirm system voltage and phase (220V or 380V, 1PH or 3PH) before installation to ensure proper compatibility. This inverter family provides reliable variable frequency control across common industrial power configurations, enabling energy savings, improved process control, and adaptable integration into existing systems.
