SSROZ and ENCLOSURE
A Solid State Relay, or SSR, is an electronic device that uses low voltage input to switch high voltage on or off. It is used in Christmas displays to allow the controller to switch the lights on and off. This article will show one who is not familiar with the device a basic overview of how it works. There are two types of SSRs, AC SSRs (the most common) and DC SSRs. As most Xmas lights are AC powered (110VAC or 24 VAC), DIYC members will use a AC Power SSR to switch or dimm the lights.
