    Product Advantages


                        K20 Series Economical VFD (5.5~7.5kW)(图3)


    Optimized structure design

    1: Three sizes for 0.75~7.5kW, reasonable power distribution, high cost 

        performance;

    2: Independent air duct design to prevent dust from entering the inverter.

              

                   K20 Series Economical VSD (0.75~2.2kW)(图3)


    Optimized hardware and software design

    1: Long life components selection;

    2: More reasonable layout of components, better MEC performance, 

        strong anti-interference ability;

             

                     K20 Series Economical VSD (0.75~2.2kW)(图4)



    Build-in high thermal conductivity insulating material

    1: Alumina ceramic substrates are used for IGBT heatsink;

    2: IGBT inside temperature is reduced remarkably, the frequency inverter 

        has better environmental adaptability.

                 

                         K20 Series Economical VSD (0.75~2.2kW)(图5)
