solid state relay?
I'm working on an electrical project in which I need to find 2 SSR's 12V (of course) with a 12V DC load capable of 5A minimum, 6-7 would give me a good margin of error. I've been looking everywhere for this and I Can't find one anywhere. Mouser and places like that have plenty which have 120/240VAC load circuits in them, but I need a DC load. I contacted one electronics company in town and the best they could do was an industrial grade product which cost $150 for the pair after shipping!!!
does anyone have any idea where I can find one? I have a $2.50 40A SPDT mechanical in there right now, it works great, but the application has it clicking on and off too frequently, it make too much noise and will reach its operational MTTF too fast at this rate! of course for the cost of those I could replace them for years and years before I'd equal the cost.
TIA

I just googled "DC solid state realys" There are tons of sites.
Let us know how you make out.
Good luck.
