I have recently purchased an 8-channel SSR to be controlled via an Arduino Mega 2560. I use mechanical relays all the time. I'm new to SSRs, so can someone tell me why you are only supposed to control A/C loads and not D/C loads with them?
Thanks
You can control DC loads with them, if they are DC SSRs.
This explains it pretty well:

Indeed. There are two types of SSR. The ones you have, and the ones you need. ;D
MIc, thanks - great article.
And indeed, I have bought something I should not have. But being a good builder, I will find a use for it in the future. :)
