HE1AN-AC240V

HE1AN-AC240V is a power relay, designed to switch very high-current electrical loads. This type of power relay works by using an electromagnet to open or close an electrical circuit at the connected switch point. Power relays are commonly used in automation and home applications where power is needed to control an electrical load. The main advantage of using a power relay in these applications is its efficiency and long-term reliability.

The main application field of the HE1AN-AC240V is industrial applications like machines, pre-assembled boards, robotics, industrial cooling units, and other high-current electrical loads. It is also used as a power relay in home applications, such as connected lighting systems, security systems, and pumps. The HE1AN-AC240V is also used for time switching and delayed control systems.

Working Principle

When the current reaches a certain level, the coil in the power relay magnetizes and thereby closes the contact points. This is done by means of an electromagnet. The contact points can be opened or closed depending on the type of power relay employed. When the system is at rest, no current is flowing and the contact points are open. When the current crosses the certain level set by the user, the contact is closed.

The contact points are connected to a number of additional devices, like the input contacts which control the voltage, the output contacts which connect or disconnect the load from the supply, and the control contacts which regulate the contact points. Depending on the type of relay, the contact points can also be adjusted. Depending on the type of load, different settings can be used.
