DC to AC Solid State Relay with 40A Load Current
The SSR-10DA / SSR-25DA / SSR-40DA single-phase solid state relay is designed for electronic switching of AC loads using a DC control signal. Unlike conventional electromechanical relays, the SSR uses semiconductor switching without mechanical contacts, making it suitable for applications requiring frequent switching.
The control input operates from 3–32V DC, allowing the relay to be controlled by a wide range of controllers and electronic control systems. The output is designed for 24–380V AC, with available versions rated for 10A, 25A or 40A load current.
The Solid State Relay is suitable for controlling heaters, lighting, electromagnetic loads and other AC consumers in automation and control systems.

Applications:
The SSR relay can be used in automation systems, heater control, temperature controllers, lighting systems, machinery, electrical control panels and other applications where a DC control signal is required to switch an AC load.
Important: The rated load current depends on the selected version — 10A, 25A or 40A. Continuous operation at higher currents may require appropriate heat dissipation depending on the actual load and installation conditions.
