Power Adapter for DE-5000
<< < (3/6) > >>
David Hess:
I am having the same problem looking for a better fitting plug.  The one I have is barely long enough and some are shorter.
graybeard:
I was lucky enough to find a power connector that worked in my junk parts collection.  It was part of an long dead universal power adapter kit.  I saved this and two other connector from that kit. 

It is just long enough to work with the DE5000.  However a 12mm long one would surely work better.  The plug in my universal adapter set I got from Amazon last year is too short.

The main thing I like about using an external power supply is it disables the automatic power off (APO).

I put an 11V Zener diode (from a bag of misc Zeners in my stock) across the dual banana plugs to protect against stupid operator error.

That is my concern and why I inquired about it here.  I could design a fault proof USB to 9 volt converter but consumer stuff is notoriously cheap.

wouldn't be easier to get (or make) a power extension cord?

I could, but a smaller and thinner power cord in the form of a USB cable would have advantages.  Even an existing AC to USB brick and then USB to 9 volt cable would be less encumbering.
