understanding power relay: its functionality, types, and applications
Release time:2025-06-15 21:41:12
A Power Relay is an essential electrical component in modern electrical systems, serving as a key device for controlling high-voltage or high-current circuits. Its primary function is to act as an automatic switch that allows a low-power control circuit to turn on or off a high-power circuit, without direct human intervention. This article explores the working principle of Power Relays, their types, and applications in various industries.
What is a Power Relay?
A Power Relay is an electromagnetic switch that uses a control signal to open or close a circuit, thereby enabling or disabling the flow of electrical current. The relay typically consists of a coil, an armature, contacts, and a spring. When the coil is energized by an electrical current, it generates a magnetic field that moves the armature, which either makes or breaks the connection between the contacts. This operation allows the relay to control circuits that require higher voltages or currents than the control circuit can handle.
