What is a Relay Power Supply? A relay power supply is an electrical system that employs relays—electromagnetic switches—to control the flow of electricity. Relays function by creating or breaking electrical connections based on a control signal. In the context of a power supply, relays are used to switch power on and off, regulate output voltage, provide overload protection, and distribute power across various components of a system. The basic working principle of a relay is simple： when an electrical current passes through a coil inside the relay, it generates a magnetic field that pulls a movable armature to close or open contacts. These contacts either allow current to flow to the circuit or disconnect it, depending on whether the relay is energized or de-energized. This on/off control mechanism can be applied to a wide range of power supply operations.
