Power Relays, Over 2 Amps: HE1AN-AC120V Application Field and Working Principle

Power relays are electrical switches that use much lower power to control a higher power application. HE1AN-AC120V is a power relay that has a maximum current rating of over 2 amps. It is an ideal power relay option for a variety of applications, from industrial motor control to home automation and beyond.

Components and Specifications

HE1AN-AC120V is a socket-type power relay with selectable input and output voltage of AC 120 Vac at 50 Hz/60 Hz. It features two-contact construction, 8 pins, and 30 mm of mounting depth. It has an operating temperature range between -23° and +65°C and a storage temperature range between -40° and +85°C. The relay has a pickup voltage range between 85-110% of the nominal voltage and dropout voltage range between 15-30% of the nominal voltage. Its contact material is silver cadmium oxide (AgCdO) with a contact rating of 10A at 120V AC and a maximum switching power of 780VA. It has a rated insulation voltage of 500V AC between contacts and coil, and between contacts and ground.

Applications

HE1AN-AC120V has a wide range of applications. It can be used for high current switching applications, such as motor control, lighting control, and more. It is also suitable for use in applications with current spikes, such as electric vehicles, solar energy applications, and power converters. Additionally, it has the ability to be applied to home automation, HVAC systems, industrial control, and more.

Working Principle

The HE1AN-AC120V power relay works by using an electromagnetic force generated by the current passing through a coil to operate the contacts. When the current passes through the coil, it produces a magnetic field which attracts the contacts. As the current in the coil increases, the force of attraction also increases, thus allowing the contacts to open or close. The contacts are spring-loaded and are normally in the open position. When a current is passed through the coil, the magnetic force overcomes the spring force, thus closing the contact. As soon as the current is removed, the contact reopens due to the spring force. This switching action is used to control the higher power application that is connected to the contacts.

Conclusion

HE1AN-AC120V is a reliable and versatile power relay with a current rating of over 2 amps. It is designed for a wide range of high current switching applications, such as motor control, lighting control, and more. Furthermore, it can be used for applications with current spikes, such as electric vehicles, solar energy applications, and power converters. The power relay works by using an electromagnetic force generated by the current passing through the coil to operate the contacts.
