Power relays come in a wide variety of sizes and capacities. The MGN2A-DC12 is a power relay designed to work with applications requiring current levels of over 2 amps. The MGN2A-DC12 is an electric relay that can be used in automotive, industrial, and commercial applications, and has the ability to switch current over a wide range of currents and applications. This article will discuss the application field and working principle of the MGN2A-DC12.

The MGN2A-DC12 is designed for applications that require high current carrying capabilities. This relay can be used in a variety of automotive, industrial, and commercial applications where switching currents from 200mA – 5A is necessary and also requires low heat dissipation. The relay can be used in a variety of applications such as controlling lighting, HVAC systems, solenoids, and door locking systems. The relay is also suitable for use in applications where low electromagnetic noise is important.

The MGN2A-DC12 contains two sets of contacts, normally open (NO) and normally closed (NC), which allows for switch flexibility. The contacts are made of an alloy and are highly resistant to corrosion and arcing, allowing for long life and reliable operation. The relay also features a high dielectric strength of 1500VAC, providing protection from high voltage wiring.

The MGN2A-DC12 utilizes a single coil latching mechanism to switch the contacts between the NO and NC positions. The latching mechanism is activated by applying an initial voltage pulse to the coil, which actuates the armature and latches the contacts into the NO or NC position. To switch the relay back to its other position, a negative voltage pulse is applied. This design ensures that the relay stays in its set position until power is removed.

The MGN2A-DC12 contains three terminals: the coil, common, and NO-NC. The common terminal is connected to the load, while the coil terminals are connected to the electrical system providing the control voltage. When the control voltage is applied, the coil creates a magnetic field which causes the contacts to move between its NO and NC positions. To switch the contacts back, the negative voltage pulse is applied and the contacts move back to their original positions.

The MGN2A-DC12 is UL and CSA listed for indoor use. This ensures that the relay meets safety requirements and can be used in commercial and industrial applications. Additionally, the relay offers maximum safety with ratings up to 60A and a maximum operating temperature of 85°C.

Overall, the MGN2A-DC12 is a versatile and reliable power relay designed for applications requiring current levels of over 2 amps. Its latching mechanism allows for the contacts of the relay to remain in their set position until power is removed, and its UL and CSA listings ensure that it meets safety requirements. With its wide variety of applications and capabilities, the MGN2A-DC12 is an ideal solution for any automotive, industrial, or commercial application.
