Resurecting a thread, would something like this be suitable for powering the electronics in the hangar with the other electrical equipment "off line"?

Yeah . . . sort of. Waayy back when I had
a good source for the line of Samlex fixed
voltage, overload protected "bricks",
I think I was able to offer a 14v switchmode
power supply good for 20A for under $100 . . .
but that's putting a stretch on the gray matter.
How about spending a few more $ and getting
a piece of test equipment. Here's fully
instrumented, adjustable supply good for
a lot more snort.

It's on sale for the next week or so. I
have several supplies of this genre' that
have been helpful in recent battery performance
studies.
Best yet, this supply gives you a real-time
suite of values on the load. You can set
it for 14.5v, max current and clip it in
place of the ship's battery. Everything
up to and including 10A of load is characterized.
You can MEASURED real time operating loads
of the ship's electro-whizzies.
After the project it finished, it becomes
valuable bench test tool. I've got more
power supplies than any other class of
tool. They range from a 30V 0.25A current
limited HP supply that came off my bench at Numec
in 1964.
Big daddy is a 40V/40A HP 'boat anchor' I got for cheap
off eBay probably 30 years ago . . . still
works great. I'm getting ready to move it
from my electronics bench in the house
out to the mess-making shop where I have
a 240v feeder that will allow me to access
the supply's full capabilities.
The short answer is: For a few dollars more
you can acquire a test tool with a lot more
present and future value than the "brick".

Un impeachable logic: George Carlin asked, "If black boxes
survive crashes, why don't they make the whole airplane
out of that stuff?"
