    Veikong solar pump inverter is really in very good quality and we also prepared some promotional products for exhibition. We are going to make new orders soon. Last year there was only one local agent and this year, there are more than 8. Some of them only sell Veikong!

    It’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.

    VEIKONG VFD500 output frequency is stable when the others are fluctuating. Also output current is less than others, that’s why output frequency is higher too which can save more energy.

3.Product features 


1.Optimized SVC algorithm, stable operation in power generation. At present, most of the inverters can not work stably under the SVC control mode (especially in the case of being reversed).VFD500 can run very well, and it achives great convenience in some special applications (such as tension control in rewinding and winding) .

2.New Auto-tuning features.Auto-Tuning features optimize drive parameters for operation with induction motors as well as synchronous motors to achieve the highest performance levels possible. Optimizing not only the drive and motor performance, but also automatically adjusts settings relative to the connected machinery.New Auto-Tuning methods. VFD500 continuously analyzes changes in motor characteristics during operation for highly precise speed control.
