This paper presents a controller＇s design proposal of intelligently controlled AC contactor with wide-range input voltage.The controller can make general AC contactor be operated reliably with a wide range AC or DC input voltage（AC 24～380 V or DC 24～220 V） by using PWM control and self-adaptive adjustment in the coil＇s voltage,and realize the functions of energy saving,silent operation,less arc or no arc break,setting,display,communication,remote operation etc.Accordingly,the performance and characteristic of the contactor will be enhanced greatly and the types of product will be reduced considerably as well.
