    Mini design for inverters (≤ 2.2kW), abreast installation of multiple inverters, reducing installation space

    Flexible installation ways

    ● Multi-function and easy to use
    DC reactors are built-in inverters ≥18.5kW

    The braking unit is built-in and standard for inverters ≤37kW but optional for inverters of 45-110kW

    Inverters (380V; ≥4kw) support the DC bus sharing solution

    Support of external keypad
    GD20 series inverters can be configured with LED keypad which has the data copy function to upload or download the parameters.

    ● Diverse Application Requirements
    Simple PLC, multi-speed control, built-in PID, torque control, multi-point V/F curve, multiple braking methods, instantaneous power failure without stopping, etc.

    ● Applications
    Vector control platform products, powerful, excellent performance, can be widely used in small and medium power applications, such as food machinery, plastic machinery, ceramic equipment, petroleum machinery, cable machinery, air compressors, machine tools, woodworking machinery, textile machinery, printing and packaging equipment, chemical equipment, environmental protection equipment, transportation equipment, etc.
