POWER SUPPLY ENDURANCE TEST
POWER SUPPLY ENDURANCE TEST
(OP)
We have a small power supply (45 watts, 3.75A at 12VDC) want to know how long it will last. Any idea what would be the quickest way to determine this...not withstanding the manufactures word on it. Could load it down and run the heck out of it. Heat it up etc. Ideas?
Thanks
Thanks





RE: POWER SUPPLY ENDURANCE TEST
Probably the fastest way to verify or refute the manufacturer's assertions is to engage an expert to reverse engineer and analyze the power supply and estimate its service life based on known data about each component and the way they interact with each other.
... which does not mean that it's actually a fast process.
The military uses it, because their stuff has to work.
The automotive industry uses it, because their stuff has to work, too.
( ... and the demonstrated improvement has driven down the fleet replacement rate so far as to produce a global capacity glut, but that's another discussion. )

Hah, I'm laughing while reading your post because I see that silly stuff quite frequently. Program managers who don't understand mathematics enough to know what 13 (in)signifigant figures means are running a lot of shows in aerospace. When a nice report is created because the PM thinks that is a more important delivery item than the product actually working, then you end up with the situation desicribed in Operahouse's post right before yours.
