Power supply

Newzed

Does anyone have a power supply that will deliver at least 18VDC @ 2.5 amps.· Have a stepper project but no power supply.

Thanks

Thanks, Stephen, but that is not exactly what I was looking for.· I am using three laptop power sypplies rated at [url=mailto:18VDC@1.7A]18VDC@1.7A[/url] for my Supermill and they wrok great.· I was hoping to find something with a bit more current capability but one of those laptop supplies would do me quite well.

hi sid ,
google for converting desktop computer supplys and put them in series
there are several articles on how to do it, ive got three of them in series right now driving my cnc, works good and is cheap, just be sure to follow the instructions

ps if you daisy chain them in series, make sure the first one doesnt have a ground from its board to its case.
i cut off the trace that did that on my first one.

Sid,

Take a look at www.mpja.com, In my opinion they are the 'King' of surplus power supplies! Here's a switcher rated at 18 VDC @4.2A:

If your voltage can go say 24VDC or more they have more choices in that range.
