VFD Frequency Inverter 2.2/3/4/7.5KW — 110/220V 1/3P Input, 3P Output | CNC Motor Variable Frequency Drive Converter

Overview: Compact, industrial-grade variable frequency drives designed for CNC and general speed-control machinery. These VFDs deliver wide-range speed regulation with robust protection, strong heat management, and a removable panel for remote interface connection. Ideal for pumps, compressors, extruders, winders, mixers, elevators and other motor-driven equipment. Control and performance: Uses an advanced control method to provide high torque, precise speed regulation and a broad speed range. Supports up to 816-segment speed programming, program running, and 4-segment acceleration/deceleration switching. Construction and components: Housings are molded from ABS flame-retardant material with a non-corrosive coating for improved crash resistance and fire safety. The design helps prevent nuisance tripping and withstands challenging supply conditions, temperature, humidity and dust. The internal capacitor is rated to tolerate temperatures up to 105°C (compared to ordinary 80°C units). Cooling and airflow: Each drive features fan cooling plus a built-in heatsink for effective thermal management. An independent air duct separates electrical components from contaminants, making the unit suitable for harsher environments. Interface and display: The front panel is removable and can be connected to the appropriate interface for remote control. The layout is logical and the digital display is clear and easy to read for daily operation. Protections: Multiple protection mechanisms are incorporated to ensure reliable operation, including overload protection, fuse protection, and overvoltage/undervoltage protection. Applications: Suitable for machinery such as winding machines, mixers, extruders, slitter winders, compressors, ventilators, pumps, grinders, elevators and other speed-control systems.
