This is a rather old post, but I hope there is someone who still uses one of these. I lost my AC/DC adapter and unfortunately it has a dual DC outlet: 9Volt + 28 Volt. It is a 3 Pin PLug, so I assume it has a common negative. Who can tell me which are the other ones? Tnxx in advance, Boy Bakhuys the netherlands. PS I don't use it as a pen plotter, but as a vinyl/ stickercutter btw. |

I’m sure I can ship it if you’d like it? |

One of these? Looking onto the face of the plug, flat side down: top-center: common ground bottom left: 39.5V bottom riht: 13.5V Voltages measured unburdened edit: I thought them a little high ( for the specs on the sticker) so I hooked them up to a load. They stick exactly to their voltages, all the way up to 1.1Amp. And on a scope, no wave or noise, nicely flatlining at all timebases. I was expecting a badly flattened half-have, and maybe my load was showing peak rather then rms. But none of that, there must be a proper lineair regulator in there, but then, why so much over spec? Would the regulator go off this much with age? Anyway, you asked for the pinout, they are above. |
