Tayfun from TurkeyVeikong 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!
Cristian from ChileIt’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.
Brahim assad from SyriaVEIKONG 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.

|Built-in PLC, multiple speeds|
It realizes up to 16 speeds via the simple PLC function or combination of DI terminal states
|Built-in PID||It realizes closed loop control system easily.|
|Auto voltage regulation (AVR)|
It can keep constant output voltage automatically when the mains voltage fluctuation.
|Overvoltage/ Over current stall control|
The current and voltage are limited automatically during the running process so as to avoid frequently tripping due
to overvoltage/over current.
Rapid current limit
|It can auto limit running current of frequency inverter to avoid frequently tripping.|
Torque limit and control
(Excavator characteristics) It can limit the torque automatically and prevent frequently over current tripping during the running process.
Torque control can be implemented in the VC mode.
