    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 5.5kw to 500kw 50/60Hz online soft starter for ac motor


Key Feature


1, Six group parameters convenient in one soft starter to different power motors load.


2, Dynamic fault recording function and Inspecting motor feedback to realize closed loop control to give best motor start up in different conditions and different loads.


3, 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.


4, Reliable quality Assurance:using computer simulation design;SMT Production process;Electromagnetic Compatibility Excellent.

Performance;High temperature aging,Vibration Test before delivery of the machine.


More control methods


VEIKONG S6000 soft starter with 6 kinds of start-up mode, 12 kinds of protection, two parking.

To MCU as the core, the use of intelligent digital control for a variety of load squirrel-cage induction motor start; allows the motor under any conditions can be smooth start, a good protection of the drag system, reducing the starting current on Power grid impact, to ensure reliable start of the motor: smooth deceleration stop, drag the system to eliminate the reaction of inertia: a complete system protection, extend system life, reduce system cost, improve system reliability: compatible with all start The various functions of the device, is the traditional star triangle, since the anti-pressure relief
