In some cases the car's relay sockets will stick, so how can this be avoided? Let's find out together.

It is the resistance of the coil that limits the current in the DC relay coil. Using AC requires a significant increase in voltage due to the inductive reactance of the coil.

Some people have a lot of confusion when choosing DC relays or AC relays. For example: the relay input is DC and the output is AC; or you want the input to be AC ​​and the output to be DC

High-voltage DC relays are widely used in various fields. The field of new energy vehicles is an important field of application of high-voltage DC relays.
