Another type of SSR, called a ‘random turn on’ solid state relay, is used to implement dimming. It works the same way as a normal SSR, except that there is no zero-crossing detection circuit.

As [Mic] often got requests to make high-power switching boards, he recently finally gave in and designed the one shown above based around a solid-state relay. Some of our readers that already ...

Solid state relays (SSR) are electrically operated switches with no moving components and are used to isolate circuits or batteries, detect faults on transmission and distribution lines, and control ...

Time delay relays and solid state timers use solid state electronic devices to provide a time delay. They may have displays, pots or other means of operator interface. They may also have ...
