Understanding Power Relay: Applications, Features, and Working Principles
A Power Relay is an essential electrical component that plays a crucial role in controlling large currents and high-power loads. Used across various industries, Power Relays allow users to control high-voltage equipment with a low-voltage signal, offering safety, efficiency, and reliability. In this article, we will explore the basic features, applications, and working principles of Power Relays, highlighting their significance in modern electrical systems. What is a Power Relay? A Power Relay, also known as a high-power relay, is an electromagnetic device designed to switch high currents on and off using a low-power control signal. It is made up of an electromagnet, which generates a magnetic field when current flows through it, and a set of contacts that control the flow of electricity through the circuit. The relay’s contacts can either be normally open (NO) or normally closed (NC), and the relay switches between these states to control the connection of the load.
