Release time:2025-08-26 22:58:28
The 220VAC Power Relay is an essential component used in controlling high-voltage AC circuits, commonly found in household appliances, industrial machines, and various automation systems. This article will explore the workings of a 220VAC Power Relay, its applications, and the critical factors to consider when selecting and using one.
What is a 220VAC Power Relay?
A 220VAC Power Relay is an electromechanical device that allows low-voltage control (typically 5V or 12V DC) to operate high-voltage AC circuits, usually at 220V AC. It functions as an electrical switch, where a small voltage is used to control a larger current, making it indispensable for controlling high-power electrical systems safely and efficiently.
Basic Construction and Working Principle
The 220VAC Power Relay consists of several key components：
Electromagnetic Coil： This is the heart of the relay. When a low-voltage current flows through the coil, it generates a magnetic field. This magnetic field attracts or repels a movable armature connected to the switch contacts.
