A 15A Power Relay is a vital component in modern electrical systems, playing a crucial role in controlling large electrical loads with small control signals. Its versatility and efficiency make it an essential element in both household and industrial settings, where reliable switching of high-current circuits is needed. In this article, we will explore the working principle, features, applications, and selection criteria for a 15A Power Relay.
Working Principle of a 15A Power Relay
A relay is an electromagnetic switch that enables the control of a high-power circuit using a low-power signal. The 15A Power Relay operates on this basic principle. When a current flows through the control circuit (often a low-voltage DC signal), it energizes an electromagnet inside the relay. This electromagnet generates a magnetic field that pulls a set of contacts together, thus closing the circuit and allowing current to flow through the connected load. Conversely, when the control signal is turned off, the electromagnet is de-energized, and the contacts return to their default positions, opening the circuit and stopping the flow of current.
