Information

The working principle of the best and cheapest 750V DC Contactor is to make the starting coil resistance small and keep the coil resistance large.When the 750V DC Contactor initially works, the coil is kept short-circuited by the starting contact of the 750V DC Contactor. At this time, only the starting coil of the best and cheapest 750V DC Contactor works, and the coil current is relatively large. At this time, the coil current of the best and cheapest 750V DC Contactor is the starting current, and the electromagnetic attraction is the initial electromagnetic attraction.

750V DC ContactorAfter the best and cheapest 750V DC Contactorworks again, the starting contact is disconnected, and the holding coil of the 750V DC Contactor starts to work at this time, and the coil current is small. At this time, the coil current of the best and cheapest 750V DC Contactor is the holding current, and the electromagnetic attraction is the holding electromagnetic attraction.

During the detection and operation of the best and cheapest 750V DC Contactor, the power supply at the control terminal should try to supply power to the best and cheapest 750V DC Contactor in a step-by-step manner, and it is recommended that the voltage rise time should not be long.
