12v Power Supply Unit specs
« on: May 21, 2015, 08:51:47 PM »
Hi!

I swapped some PSUs while moving things around and I'm not quite sure what was the Atmegatron PSU anymore.
The one I suspect is the right one is a 12v PSU at 2A. That PSU doesn't show the polarity but testing it on my multimeter shows that the positive is at the center.

Can someone confirm if this is the right PSU for the Atmegatron? Thanks!

Hi,
Yes that's correct.  You can get suitable ones from most electronics shops and online.  The full spec is:
12V, 2A (or greater - def not less), 2.1mm DC plug, centre positive.

Thanks!
I confirm!
After your reply, I tried that PSU and it worked.
I was a bit anxious to damage the Atmegatron by plugging the wrong PSU.

Cool, that's good news!  There's protection for reverse polarity and PSUs up to 24V, so it's pretty robust.  Anything over 24V and smoke may start to appear though!
