It means that a federal bureaucrat has decided that the design and
manufacturing system meet FAA standards, and thus the part can be sold
as an aircraft component.

Since the FAA standards are a bad joke, it doesn't mean the design and
manufacturing system are actually adequate.

The best (but not legal) solution would be to save the box, and to have
someone with a clue build you a real inverter (it's not hard) and then
seal the box up again.

Had a couple of these inverters powering the AC sync-type fuel flow
indicators in a couple of Beech 18's. The third aircraft had the same
fuel flow lash-up, but was powered by a 6.5 lb motor-verter.

Only had issues with one of the solid state inverters, am thinking it
was an older version of the same unit. I'm assuming the construction
"standard" has changed a little. I could get to the parts inside it,
but they were truly potted in place.

It was by no means a high-tech unit, but the construction at that time
was decent.

One of my all-time favorites is a Honeywell/Grimes 70-0196-1 "solid
state flasher unit". 28v 1.0-5.5 amp input. About the size of a turn
signal/warning light flasher if you potted it into a neat little
anodized aluminum box (hint hint) and ran a couple of wires out the
top. Used to make the red light bulb on the top of a
Chieftain/Cheyenne blink.

Current list price-wait for it-$1035.61, but available at your local
Aviall branch for only $880.27 (order it online, they'll throw in the
shipping).
