[Elecraft] AC Adapter Power Supply For KX3

[Mike Cox]

I'm using a DIN rail mount commercial supply made by Mean Well, model 
MDR-40-12. It's a switcher, it's small, and I've had no noise issues. 
It's output is adjustable from about 12 to 15 Volts (screwdriver 
adjust). The continuous current rating is 3.3 Amps.

You can find them through a Google search. I bought mine from TRC 
Electric though I see that Mouser and many others also have them. Being 
a commercial supply, you must provide your own line cord (attaches via 
industrial screw terminals). TRC had them for under $25 though their 
shipping was a bit steep.

I'm not the only one I know of using this model supply with a KX3. I've 
heard no complaints.

Mike,
