12V power relays are electro-mechanical devices that are used to control high-power circuits with low-power signals. They operate by using an electromagnet to control the switching of a circuit, typically used to switch a load on and off.
The 12V in the name refers to the voltage required to activate the electromagnet in the relay. This voltage is usually supplied by the electrical system of a vehicle or by a battery in an off-grid application. Power relays are commonly used in automotive applications, such as controlling headlights, air conditioning systems, and power windows. They are also used in industrial settings to control large motors, pumps, and other high-power equipment.
12V power relays provide a reliable and efficient way to control high-power circuits with low-power signals, making them an essential component in many different types of systems.
12V power relays can be used in a variety of applications where a low power signal needs to control a high-power load. Some common examples of where you might use a 12V power relay include:
12V power relays are versatile components that can be used in a wide range of applications to control high-power circuits with low-power signals.
