Compact Switching Pwr Supply

[Jim Brown-10]

Sometime in the last week or so someone was asking about this.  Last
year, in preparation for a DX trip, I bought a Powerwerx SS-30DV from
Ham Radio Outlet for about  $110-$120. It's quite compact -- 5 inches x
6 1/2 inches x 2 1/2 inches and light weight, and is rated to run a 100W
rig.  As it turns out, I didn't take it on the trip, so it hasn't
received its baptism of fire operating a K3 during a contest. :)

Yesterday I found time to check it out for RF trash, and couldn't find
any in the ham bands on the antennas that are nearest to my operating
desk -- a 160M vertical about 25 ft away, and an 160/80/40 wire dipole
about 120 ft above the shack.  That doesn't mean that there isn't any
noise -- I have ,my share of noise from my neighbors appliances.  I
checked the ham bands from 160M through 6M.

This PSU has a standard IEC jack for the line cord, Pomona (dual banana)
jack on the rear panel, and two pairs of Power Poles on the front panel.

Hi Jim,

Are the front panel APP sockets the 30 AMP variety?  Seems like they
should be, given the output current spec.

They are the same connector as used on the K3. There are two pairs.
