    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!

    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.

Product Description

380V/440V 7.5KW 11KW 15KW 30KW 45KW To 500KW AC Motor Multi-Function Soft Starter


Key Feature


1. Reduce the starting current, reduce power supply Peak current, reduce the cost of Distribution Equipment. Reduce the abrasion of Motor, Improve the service Life of Mechanical Equipment.


2. Optional parameters are starting Convenient in one soft Starter Different starting motors.


3. Inspects Motor Feedback Voltage Soft Starter to Realize Closed loop Control, Motor Start-up Ensure the success in Different Conditions and Different loads.


4. A Variety of Ways starting: Voltage RAMP starting Way can get the maximum output torque; Current limiting can Realize Biggest Limitations of the Start soft starting current.


5. Reliable quality Assurance: using Computer Simulation Design; SMT Production Process; Electromagnetic Compatibility Excellent Performance; High temperature aging, Vibration Test before Delivery of the Machine.


6. Perfect and Reliable Protection function: Loss of Voltage, less Voltage, over Voltage Protection; Overheating, TOO Long starting time; Input Phase Lost, Lost output Phase, Three-Phase imbalance; starting over current, overload and load Protection Short circuit, etc .


7. Full-field Bus Monitoring Dynamic Control Starter, Easy Networking.


8. LCD Screen can display displaying parameter code, State and error.
