WHZD Series Intelligent Magnetic Starter / Electric Motor Soft Starter

Description

WHZD series smart protector applicable to an evectromotor is applicable tohe circuit with the alternating-current supply voltage 24-660V, Frequency 50Hz or 60Hz, combining the ACContactor and other switches to be an electromotor for controlling the circuit. It can be three-phase electromotor' s lose phase when three phase alternating-current is unbalanceorov erload protected. If the second circuit appears lose phase or three phase alternating-current is unbalance or overload while electromotor isworking, the protector will immediatelycut off the current supply. So it can protect the electromotor credibly. This equipment adopts the circuit withpunching cores' current, and controls the circuit with the inside nicety voltage comparator, and the output port is contactless solid AC electronic switch, (whichcan' t use multimeter resistance standard when xamineing the make-break capacity).

Functional description

1, Overload protec t: When the working current of the motor exceeds its rated current 1.2-5 times the delay-action time of the protector is 14S-0.3S. It has excellent renersetime limit function Phase failure protect: When any one of the three phases is failed, T≤ 2SBlock protect: WHen the working current reaches to 8times even more of the machine current lower than 0.3S Three phase current unbal ance protect: Any tow phasecurrent of the three Phase are weadl ower than 10S Under-voltage protect: The working power supply range 35-70%., the rated working power upply lower than 10S
2, LC1 AC Contactor Function Mechanical more than 1 million times; Voltage: AC 380V +/- 15%; Frequency: 50/60Hz +/- 2%; Protector consumption lower than 2W; The matches voltage: 85%-110%US; Release the electric voltage: 75%-20%US
