HG2-DC12V

Power Relays, Over 2 Amps: HG2-DC12V application field and working principle

A HG2-DC12V power relay is a kind of high-current switch that uses electromagnetism to open and close the internal switch. It is mainly used for switching devices in high-current circuits, and its switching capacity can reach more than 2A. It has many uses, such as motor control, light switch, and other applications.

Application fields:

• Motor control: HG2-DC12V power relays are widely used in motor control. Mainly applied to the circuit of motor-driven equipment, it can be used to cut off the interrupt power supply when the motor fails to start and cause the equipment to crash or be damaged severely.
• Light switch: HG2-DC12V power relays are also used in light switches. For example, on street lights, it can be used to control the opening and closing of the street lights and improve their energy efficiency.
• Other applications: HG2-DC12V power relays are widely used in security alarms, medical equipment, information appliances, industrial control, energy management, energy saving and other fields.

Working principle.

The HG2-DC12V power relay adopts the split-coil structure with two internal coils of different directions. When the load is electrified, it generates an alternating magnetic field that interacts with the two coils of the relay. When the alternating magnetic field reaches a certain intensity, it produces an electromagnetic force. Under the action of the electromagnetic force, the armature of the relay is pulled near the core of the relay, thereby causing the switch contact form of the relay to deform and change, thus opening or closing the internal switch of the relay.

The HG2-DC12V power relay has many excellent features, such as high switching capacity, high power, fast response, large current carrying capacity, long life, and low cost. So it is widely used in various application fields.
