Working Principle

The MK3P-I DC12 power relay works on the principle of magnetic attraction. It consists of an electromagnet which is energised by an AC or DC voltage, creating a magnetic field. This magnetic field attracts the movable contact, causing it to close the electrical circuit between the two poles. When the voltage to the electromagnet is switched off, the magnetic field disappears and the movable contact is then released, reopening the electrical circuit. This simple electrical circuit design makes the MK3P-I DC12 power relay a suitable choice for applications which require a high switching capacity.

Application field

The MK3P-I DC12 power relay is most commonly used in LED lights, HVAC controls, in-car electronics, industrial automation processes, electric motors, charging circuits, and home appliance controls. Its flexible and reliable design makes it suitable for a variety of different applications, making it a desirable choice among many engineers and technicians.
