[Elecraft] Which of these would make the best power supply for the K3(S)?

I'm looking at the Meanwell power supplies because they are cheap and seem
to be well regarded. I've come up with these two choices, feel free to give
more suggestions of other models. I've seen talk on this reflector of
supplying more than 13.8V to the K3S so that's why I'm looking at the 15V
model.

12V Model:   Meanwell NES-350-12
Voltage range 10-13.5V
29A


15V Model:   Meanwell NES-350-15
Voltage range 13.5-18V
23.2A


The 15 volt model would seem to be the obvious choice, except that it
doesn't supply the recommended 25 amps. The K3S manual says 22 amps typical
though.

Is there another model Meanwell I should be looking at that has better
protection or filtering?

I've already got an Astron switching power supply, the Meanwell would be a
second alternative.
