Power Relays, Over 2 Amps

Power relays play an important role in modern applications in a number of different settings, from industrial applications and robotics to everyday consumer electronics and much more. The 2981981 power relay is one of the most popular and commonly used, and has a wide range of applications, as well as a number of useful features. This article will explore the various applications and working principles involved with this type of power relay.

Application Field

The 2981981 power relay can be used in numerous applications, including industrial operations, motor control, robotics, video or audio equipment, lighting control, automotive applications, home electronics, and many more. It has a wide range of current handling capabilities, with load ratings from 2 amps up to 20 amps, and can be used in both AC and DC circuits, making it a highly versatile and useful device. Additionally, it has a high insulation rating of 4000 volts, meaning it can be used in high voltage environments without any issues.

Working Principle

A power relay is essentially a switch which allows a small amount of current to control a larger amount of current. When a small current is applied to the coil of the relay, a magnetically-driven armature is drawn to the center of the coil, making physical contact with two metal contacts and in turn connecting two larger conductors. As long as the small current is applied, the contacts will remain connected. As soon as the current is removed, the spring loaded armature will return to its starting position, opening the contacts and disconnecting the two larger conductors.

Other Features

In addition to its great versatility and high insulation rating, the 2981981 power relay has a number of other useful features, including a long service life, a high dielectric strength, and an impressive temperature range. It has an operating temperature range of -40°F to +185°F, giving it an advantage in applications which require a wide range of environmental temperatures. Additionally, it has a high dielectric strength of 1000 volts per minute, meaning it can handle high voltages with ease and ensuring a safe operation.

Conclusion

The 2981981 power relay is a highly versatile and effective device, with numerous applications in different fields and a wide range of features that make it a great choice for many types of operations. Its wide range of current handling capabilities and high insulation rating make it an excellent choice for applications involving high voltages, while its long life and high dielectric strength make it a great choice for any application requiring a reliable and robust switch.
