The good price and quality 750V DC Contactor product works on the principle of electromagnetic conversion. From the point of view of product function classification, the 750V DC contactor is a classification name of relay. The structure of the good price and quality 750V DC contactor product is generally different from that of the relay.
The coil of the good price and quality 750V DC contactor product generally has a larger starting current when it is turned on, and the good price and quality 750V DC contactor product is converted into a smaller holding current after it is normally turned on. Therefore, the drive power and coil control devices of the 750V DC contactor should generally be selected according to the starting current of the 750V DC contactor.
At present, the commonly used switching methods of starting current and holding current for the good price and quality 750V DC contactor products mainly include mechanical contact of the 750V DC contactor product, field effect tube delay circuit and PWM pulse width modulation circuit.
