Power Relays, Over 2 AmpsPower relays are electrical relays that are designed to switch high-power loads, typically with current ratings of 2 amps or higher. They use a small electrical current to control the flow of a much larger current, allowing a low-power circuit to control a high-power circuit. Power relays are commonly used in a wide variety of applications, including automotive systems, industrial automation, and power distribution systems. They can be used to control motors, lights, heaters, and other high-power loads, and may also include additional features such as overcurrent protection, current sensing, and PWM control.
