[Elecraft] K3 with switching power supply??

[Mike Furrey]

Looking at the specs, the K3s could draw up to 25 amps max, the KAT500 could draw up to 1 amp max and the Powerwerx supply is rated at 25 amps continuous duty. Sooooo .... It "may" be ok. That would depend on how long you hold the key down or transmit rtty. 

You can get the Powerwerx unit that contains the built in volt/amp meter or purchase the external meter unit and see what the actual current draw is on transmit.
I don't have a KAT500 so maybe someone else here has tried that combination with that power supply. I have had no issues with my K3 or FT857D or IC7200 and the LDG 200pro antenna tuner.

 Is there a problem using the Powerwerx to power both the K3S and the KAT500, or would I need a second Powerwerx?

I have been using that Powerwerx power supply since before Elecraft started listing them on their web page and it is a good, quiet power supply. I use a big linear power supply at home and the Powerwerx unit for portable operations since it is a good compact supply. I got one for my newly licensed YL and it is on all the time with her rig with no issues and no noise.
