Solid State Relay 3V~32V DC To 24V~380V AC SSR-25 DA

The Solid State Relay 3V~32V DC To 24V~380V AC SSR-25 DA is an electronic switching device designed to control AC loads using a low-voltage DC control signal. The relay accepts a wide DC input range from 3V to 32V and switches AC output across a broad mains-compatible range from 24V to 380V, making it suitable for a variety of industrial and automation applications where silent, fast, and wear-free switching is required.

As a solid state relay, this SSR provides galvanic isolation between the control and load sides, eliminating mechanical contacts and reducing maintenance associated with mechanical relays. Typical benefits include long operational life, vibration resistance, low electromagnetic interference, and rapid response for repetitive switching tasks. The SSR-25 DA form factor is commonly used for controlling resistive and inductive AC loads such as heaters, motors, lamps, and other equipment when an electronic alternative to electromechanical relays is needed.

Installation considerations include ensuring appropriate heat dissipation and mounting, observing polarity and input voltage limits on the DC control side, and verifying compatibility with load type and switching frequency. Always follow local electrical codes and safety practices when integrating the relay into control systems. This product is intended for use by qualified personnel familiar with AC mains and control electronics.
