Solid State Relay SSR-25DA 25A

The SSR-25DA is a single-phase solid state relay (SSR) designed to control high-current AC loads using a low-voltage DC control signal. Unlike mechanical relays, this SSR has no moving parts, offering a longer lifespan, silent operation, and high reliability. It is capable of switching an output load of up to 25A and a wide voltage range of 24-480V AC with a control input signal of just 3-32V DC. The SSR-25DA typically features a zero-crossing trigger method, which switches the load on when the AC voltage is at zero, minimizing electrical noise and interference. This makes it an ideal solution for a variety of applications, including PID temperature control, lighting, and motor control.
