[Elecraft] [K3] power supply question

[William Ravenel]

Dave,

The Powerwerx SS-30  is 5 x 2.5 x 6.75 inches (including the connectors on the rear). It has two Powerpole connector pairs on the front and will handle 25 W continuous/30 W intermittent. It might be a little big for the side pocket of your bag based on the dimensions you provided but I don't know if you will get much smaller in a 25A supply unless you go with the Gamma Research HPS-1a that provides 5A continuous and 25A at a 25% duty cycle.

I bought the Powerwerx supply at Dayton this year and used it for 24hrs straight at Field Day with my K3 working CW. It does have a fan that you can hear, but I've heard a lot worse and didn't notice it with the background noise at Field Day. The noise is noticeable in my shack, but I wear headphones most of the time and that takes care of it.
