Ok so I got my 24V AC/DC transformer for my gas valves and would like to use it for my SSR's (pumps) as well for the manual turn on. I'm going to run the 5Vdc from BCS for the auto turn on.(using a three way switch). Problem I am having is the only step down I can find I have to get from Hong Kong. I know some one hear has a good place to shop for this. What are you guys using Im thinking about 100W so if need be I can add to system.
