A Relay Power Supply is an electrical system that uses relays to control the switching of power sources or circuits. Relays are electrically operated switches that allow control of a high-power circuit by a low-power signal. These devices are widely used in various applications, from industrial automation to home appliances, owing to their ability to provide remote control and protection for electrical systems.

    Automation and Control Systems

     In modern automation and control systems, relay power supplies are crucial for the remote control of electrical circuits. These systems are commonly used in industrial manufacturing, home automation, and smart grids. A relay can be triggered by an external signal or system, switching power on or off as required. For example, in an automated production line, relays can control various machinery, ensuring smooth operation and reducing the need for manual intervention.
