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 engineered to control AC loads using a low-voltage DC control signal. With a wide DC input range of 3V to 32V and an AC output switching capability across 24V to 380V, the SSR-25 DA is suitable for many industrial and automation applications that require silent, fast, and wear-free switching.As a solid state relay, this model provides galvanic isolation between the control and load sides, eliminating mechanical contacts and the associated wear and bounce. Key advantages include extended operational life, resistance to vibration, low electromagnetic interference, and rapid response suited to repetitive switching. The SSR-25 DA is commonly applied to control resistive and inductive AC loads such as heaters, motors, lamps, and other equipment where an electronic alternative to electromechanical relays is preferred.Installation requires attention to proper heat dissipation and secure mounting to maintain reliable operation under load. Observe correct polarity and input voltage limits on the DC control side and confirm compatibility with the intended load type and switching frequency. Follow local electrical codes, use appropriate protective devices, and have installation and servicing carried out by qualified personnel familiar with AC mains and control electronics.
