Hi All
I've just fit some led strip lights to my campervan and face-palmed when I saw they were USB and on 5v, not 12v. I have cut the usb end off and wired to a switch panel in the van that runs off the 12v leisure battery. As a quick test, I've powered on to check all OK and fine. I can't leave them like this as they could overheat.
I purchased a 12v/24v - 5v 3a step down convertor from ebay. Connected input to van's 12v system and output to the switch (via a 5a fuse). Soon as I turn the switch on, the fuse blew.. Thought maybe a dud convertor, but same thing using a replacement sent to me.
Can anyone tell me why the fuse keeps popping and if this setup sounds ok?
Thanks a lot
