We always keep a couple of Netonix DC switches around that take in 12v and output up to 48.

Parallel hookup CAN get you more amps, but the power supplies can buck each other if they are not designed for it. You need to take that into account. bp <part15sbs{at}gmail{dot}com> On 7/11/2017 8:57 AM, Steve Jones wrote: That actually works? Does that apply in parallel as well if I have the voltage I need but not the amperage? I just assumed multiple power supplies connected together would be like crossing streams and call up some demonic stay puff marsh mellow crickets or something On Tue, Jul 11, 2017 at 10:02 AM, Chuck McCown <[email protected]<mailto:[email protected]>> wrote: Two 24 volt wall warts in series. 4 - 12 volt wall warts in series.

Your local electronics supply would be the best chance.

You have to get them cut, and the cuts not galvanized,, but its literally the same pipe (thanks sitepro for forgetting your nail polish wipe) I really figured the security joint would have it, with multicam ip cams and all.

Any other ideas on where to look in a pinch?
