    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.

 frequency range


 Input frequency resolution

Digital setting: 0.01 Hz
Analog setting: maximum frequency x 0.1%

 Startup torque


 Torque control accuracy

SVC:within 5Hz10%,above 5Hz5%

 V/f curve

V / f curve type: straight line, multipoint, power function, V / f separation;
Torque boost support: Automatic torque boost (factory setting), manual torque boost

 Frequency giving ramp

Support linear and S curve acceleration and deceleration;
4 groups of acceleration and deceleration time, setting range 0.00s ~ 60000s

 DC bus voltage control

Overvoltage stall control: limit the power generation of the motor by adjusting the output frequency to avoid skipping the voltage fault;
Undervoltage stall control: control the power consumption of the motor by adjusting the output frequency to avoid yaw failure
VdcMax Control: Limit the amount of power generated by the motor by adjusting the output frequency to avoid over-voltage trip;
VdcMin control: Control the power consumption of the motor by adjusting the output frequency, to avoid jump undervoltage fault

 Carrier frequency1kHz~12kHz(Varies depending on the type)
 Startup method

Direct start (can be superimposed DC brake); speed tracking start

 Stop methodDeceleration stop (can be superimposed DC braking); free to stop
