[Elecraft] Re: Anyone know this info about switching supplies?

[Tom Hammond]

WB:

We're discussing it here right now... what would the 'damages' be if 
a supply (ANY supply) could/would fail placing 24VDC at up to 30A on 
the K3's DC line?

I'm thinking about designing an external plug-in OVP kit.  Unless YOU 
want to do it.

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).
