How does the electric vehicle DC contactor work? How to connect?

How does the electric vehicle DC contactor work? How to connect? The electric vehicle DC contactor is mainly used to control the DC circuit (main circuit, control circuit, excitation circuit, etc.). Unlike AC contactors, the iron core of DC contactors has no eddy currents, so it is generally made of low carbon steel or industrial pure iron.

The basic principle and selection principle of high voltage DC contactor

The basic principle and selection principle of high voltage DC contactor

In a broad sense, the high-voltage DC contactor refers to the electrical technical equipment that affects the magnetic field generated between a coil current and a closed contact to control the cultural load in the electricity consumption of industrial enterprises. Contactors include AC contactors (voltage information AC) and DC contactors (voltage DC), which are used in China's power, power distribution, and power consumption.

DC contactor model connection and working principle

DC contactor model connection and working principle

The DC contactor model is a contactor whose iron core is controlled by DC. Its load can be DC or AC. The iron core of the DC contactor is different from the iron core of the AC contactor. AC and DC contactors can be selected according to the working voltage and current of the line. Let's introduce the working principle and function of the wire type DC contactor and the DC contactor.
