HC4E-L-AC12V

Power Relays, Over 2 Amps

A power relay, also known as a contactor or switch, is an electrically operated device used to control high power circuits with a low power signal, often from an automated system or a computer. The HC4E-L-AC12V is a power relay that is rated for currents of over 2 Amps and is used when higher currents are necessary.

Application Field

The HC4E-L-AC12V is a popular power relay with many application fields. It is particularly useful in industrial settings where it is necessary to be able to control high-power applications. It is used to control air conditioning systems, HVAC systems, pumps, and other electrical motors or appliances that require up to 12V of current. It is also commonly used in UV lighting systems, computer ports, medical equipment and elevators.

Working Principle

The HC4E-L-AC12V works by using a low voltage input to switch the high current applications. The relay has a control coil that when a voltage difference is supplied to it, it creates a magnetic field which triggers a mechanical switch. This switch in turn controls the high current application. The control coil can be de-energized by opening the power supply again, thus stopping the current.

Conclusion

The HC4E-L-AC12V is a popular power relay that is capable of handling loads up to 12V. It is used in a variety of applications including industrial, medical and other systems where high currents are needed. It can be easily operated by low voltage signals and is able to control the supply of high current applications.
