Power Relays, Over 2 Amps

The HE1AN-DC48V is a FET Power Relay manufactured by Omron, a world-leader in the field of automation. The relay is characterized by a switching current of 24V DC, with a rated current of over 2 amps and a rated coil voltage of 24V DC. It features full-wave rectified DC input and a power-saver mode, meaning that it consumes the lowest amount of current possible while in the active state. The HE1AN-DC48V\'s contact configuration is normally open, produced through a single throw and double break contact structure.

Applications

The HE1AN-DC48V is suitable for a wide variety of applications, such as motor load control, factory automation, temperature control, as well as lighting and backup power control. Its small size allows for it to be used in extreme environments and difficult-to-reach areas. Additionally, it can be used to switch ON/OFF various power sources, such as solar energy, in order to effectively manage a smart grid.

Its robust construction and insulation enable it to be used in a variety of applications and harsh environments, such as industrial plants, mining, extreme cold/hot temperatures, chemical factories, and even marine and offshore applications.

Working Principle

The HE1AN-DC48V is a FET (Field Effect Transistor) Power Relay. It is composed of a triac semiconductor switch, a coil, and a logic circuit. When the coil is energized, an electromagnet generates a field and the triac switches on. When the coil is not energized, a spring button de-actives the switch, allowing the current to be switched off.

The HE1AN-DC48V\'s design includes several current protection features, such as inrush current control, over-current protection, over-voltage protection, short-circuit protection, and phase failure protection. Additionally, its switching capacity allows it to be used in applications that require high currents, including motor load control, power switching, and intermittent duty cycle cycle switches.

Conclusion

The HE1AN-DC48V is a specialized FET power relay from a world-leader in automation. It is suitable for a variety of applications and harsh environments. Its features allow for it to effectively control power sources and protect against current overload, making it an invaluable tool in today\'s modern industries. With its small size and robust construction, it is an excellent choice for a power relay.
