[Elecraft] K3 - small power supply 110-240VAC

[Bud Semon N7CW]

Jorge,

Yes, we use several of the same supplies for the full 48 hours with no
problems and no RFI.  You must remove an internal jumper wire for 220V
operation.  You can see the eham reviews at
http://www.eham.net/reviews/detail/ .  I did look at the PowerWerx supply -
it is smaller and rated at 25A and the USA price is within $10.  It is
apparently brand new - it doesn't have a eham review page and it is not in
stock.  So there won't be any reliability or RFI data for a while.

Thanks Bud,

>From the manual:  "Recommended supply: 13.8VDC @ 25A, continuous duty for
K3/100;

Do you use it full 48 hours without problem during contests?  This is a 23A
PS... Anyway they have another model for 30A.

If the brand is good will consider it.

Here I only find China PS´s!..  and I wantot avoid them

Jorge,

I like the Samlex 1223.  It operates on 110 or 220, 50 or 60Hz and is very
quiet.  We used them at 9L5A last year for CQWW CW and I have used one at
home for years.

Hello,

 

Do you know about a good power supply for the K3, to be used in any country
and lightweight?

 

Thanks,

Jorge
