I have SRD-05VDC-SL-C relay that I got for my ATMEGA and I noticed that it says on the relay:
10A 250V/AC 10A 125VAC 10A 30VDC 10A 20/DC
Then I was reading this article and found this line:
Output: Connect a load, DC 30V/10A，AC 250V/10A
This is where I get lost, as far as I understood these are maximum ratings, but what does the relay output AC 220V or DV 30V?
Basically I want to power 9A 20V DC LED panel. In order to do this I still will need AC to DC converter and transform the 220v to 20v, correct? Thanks!
