Power Supply for KX3?

[Jock Irvine]

Can anyone recommend a good, small power supply to use at home with my
KX3?  I've been using a TenTec 937 but it's moving to a new QTH soon.

Thanks and 73,

Jock N1JI

Jock, I asked that very question of the Elecraft people a year ago when I built my KX3. PowerWerx was their recommendation. http://www.powerwerx.com/power-supplies/ <http://www.powerwerx.com/power-supplies/>
I now have two — one powering my K3S (or KX3), and the other powering everything else, except the KPA500 which has a dedicated house AC line.

Jack,
    I recommend the MFJ 4103.   It is small, light, efficient and
inexpensive selling for around $50.   I have two of these one for each of
two KX3s; one in the USA and one in Ireland.   I could not be happier with
them.   Take a look at it.

I use a BioennoPower BPP-120 pack full time, in the shack and portable.  Its 10 Ah lithium battery supplies the KX3/PX3 with no RFI and powers the iPad at the same time.

Handy form factor and light weight.  I never use the inverter though.

I am currently using the MFJ-1317 which is rated for about 2.9A max, seems
to work well with no noticeable noise on HF. It even had a plug of the
proper size to fit the KX3.
I notice that ProAudio Engineering now sells a PAE-Kx33 power supply which
is rated for 4A max. They claim it is RF interference free.
Of course if you plan on getting the 100W amp in the future, then the
Powerwerx power supply is the way to go.

I use an Pro Audio Engineering PSE-Kx33 for portable operation.
I don't notice any noise, even in my RF quite New Hampshire QTH.

This power supply was designed for use with the KX3. Can be used with the
K1, KX1 and K2/10 as well.

*/The power supply I purchased for my bear foot KX3 the ls50-12 by
Lambda its small was plugged in over a year until I got the KXpa-100.
It measures 4" x 4" x 1 1/2 no-on off switch cost was very reasonable

Hi Jock,

For out-of-shack (hotel / office) operations, I use the following PSU

  Triad WSU150-2400

which is available from Digkey as p/n 237-1409-ND.  $20 in unit
quantities.  I've found this unit to be reasonably RF-quiet, yet small
enough to fit in the ammo box I use to transport the KX3.

http://tinyurl.com/njdgk3j

We use similar Triad wall warts for some of the KX3 accessories, such
as the PX3.

In the home QTH shack, I use a Powerwerx SS-30DV PSU for a variety of
13.8V devices, including the KX3.  Elecraft is a Powerwerx vendor,
incidentally.

73!

Thank you everyone for all the replies and good information.  I've narrowed
it down to either a Powerwerx supply, or the PAE-KX33. The PAE-KX33 looks
great, but I'll probably go with the Powerwerx so that I have the option to
power other, larger rigs.

73,
