A local discussion has 'erupted' regarding switching poser supplies
and whether
they can fail in an UNregulated (e.g. high) output voltage condition,
or if
when they fail will they (almost) always fail in a NO OUTPUT mode?
I've never seen this happen myself, but I just added a task to my
firmware list to turn the K3 off automatically if there's a persistent
overvoltage condition (say, > 17 V for several seconds).
