K-Line Addition - DC Power Supply (Suggestion)

How do Elecraft users feel about the possible addition of a
high-quality DC power supply that matches both the physical dimensions and
veneer of the existing K-Line? The power
supply could even be sized to set above/below the new KAT500 and should, IMHO,
have multiple DC outlets such as Powerpoles® and screw lugs. I’d be willing to pay a premium for a quiet DC
power supply with very low emission characteristics. Thanks, 73, Rich, K3VAT

Re: K-Line Addition - DC Power Supply (Suggestion)

That seems a good idea except for two reasons:

1. It wouldn't work for me unless it could handle 100 amps. I have
2m and 70cm RF amps that require 50 or 60 amps and I have just about
finished replacing all of my 12v wall warts with a buss that runs
them with power from that same 13.8v PS that supplies the KLine. That
PS also trickle charges three large Server Room backup batteries that
kick in when there is a power outage.

2. I doubt Elecraft would want to get into that business due to the
already stiff competition in that area of manufacture.

Re: K-Line Addition - DC Power Supply (Suggestion)

In reply to this post by rich kennedy

In my opinion, power supplies should be relegated to something like the
AC receptacle on the wall or the 12 volt battery under the hood of an
automobile. It should do its thing, but not be obvious. IMHO the place
for a power supply is on the floor under the operating desk (or
workbench). No need for meters on the supply itself, I have measurement
stuff above the tabletop. I use an Astron 35 linear at the operating
position and have an Astron SS-30 switcher at the workbench (along with
several other lower current supplies). There are no 13.8 volt power
supplies above the desktop - If I need other voltages, yes, I do have a
+/- 15 volt supply along with +5V on the workbench along with a variable
voltage positive supply for special needs - but I don't think those are
relevant for powering the K2, K3, or KX3.

Bottom line, power supplies are on the floor out of the way and treated
just as an energy source.

So, my answer to your question is NO. The RigRunner does sit on the
desktop with fuses to match the wire sizes exiting from it.
I do not think it is in the best interests of Elecraft to attempt a
power supply design given that it would require UL compliance
certification (as well as other countries certification) which can be an
expensive process for a power supply that would likely have a volume of
less than 10,000 units even at product life end.

I would put this in the "it would be nice -- but" bucket.

*IF* Elecraft were to produce a power supply, the most economical
solution would be to use a modular OEM switchers that already has UL,
CE, CSA, etc. certifications and wrap it in an Elecraft case with IEC
cord, additional filtering, external power switch, and maybe metering.
OEM supplies - available in many quality levels, form factors and price
points - are used by several other manufacturers as the core of their
"matching" (or internal) power supply offerings.

Re: K-Line Addition - DC Power Supply (Suggestion)

In reply to this post by Don Wilhelm-4

I'd like to second Don's comments. Often the difference between a noisy power supply and a quiet one is the separation of only a few feet. The idea place for the supply is on the floor away from the receiver and freeing desktop space. I have mine paralleled with a storage battery too. That saves the QSO when the power fails (assuming I can operate in the dark).
Don mentioned certifications for each country. Don't forget the power source is often different from country to country (50/60 hertz and 120/240 vac) or even within the country (look at Japan). Building a supply that meets all these requirements adds expense. Look at the issues an internal power supply causes in the KPA500 even without the concerns of interfering with a receiver.

Re: K-Line Addition - DC Power Supply (Suggestion)

In reply to this post by Joe Subich, W4TV-4

I for one would like to see Elecraft produce a power supply optimized for
the K3 and matching Elecraft accessories. For years I owned a Kenwood PS-50
power supply and regretted selling it a few years ago. It was rock solid
and absolutely quite and yet matched my TS850S. I currently own two Astron
RS-35 power supplies, but they do not have the fit and finish of the
Kenwood. Any yes, both of mine have a small but noticeable amount of hum.
The Kenwood PS-50 fit in an enclosure that is just slightly larger than the
P3. I am sure that Elecraft would ensure top notch rf filtering, light
weight and with plenty of auxilliary outputs for running various Elecraft
devices including the KRC2, P3 and KAT500.

Re: K-Line Addition - DC Power Supply (Suggestion)

I see no need for Elecraft to produce such a simple and mass produced
product from all over the world for prices that start at dirt cheap and go
up. It would be a very limited market for sure and hams like myself
sometimes want a better product for an application that we have. There are
power supplies available that top quality and noise free if a person wants
to purchase one. I'm one who thinks that the supplies should be out of the
way for the most part my VS supplies I do like to keep an eye on to make
sure nothing has changed.

I have owned several different supplies in the past and now have settled on
4 that I have kept 2 Samlex a 1223 and a 1235 one is a spare and one is used
on my MicroHAM devices as some need connections to a power supply other than
the one radios are connected to. The other 2 are both Astron a RS and a
VS-70-M's that supply the rest of the shack and 2 amps. With all these
supplies there are no supply noise at all the Samlex is a good supply and a
QST rated best buy. You can never go wrong with an Astron Linear Supply in
the proper size for your shack.

If you're getting hum you need to do some checking on your install I would
think I have "NONE" with any of mine on my 2 K3's a K2, FTDX-5000MP or an
SRR-IQ for just a few.

Re: K-Line Addition - DC Power Supply (Suggestion)

In reply to this post by rich kennedy

I may have missed it if anyone else made this suggestion......I would like to be
able to purchase a P3-size empty case into which I could install a switching
supply board such as an Astron SS-30, with some additional filtering, in order to
have a matching supply for my K3....

Perhaps the blank boxes will become available in the future as was done with the
K2 cabinet.

Re: K-Line Addition - DC Power Supply (Suggestion)

I would not like to see Elecraft spend it's limited engineering
resources designing a power supply either. There are literally hundreds
of options available.

I like the idea of Elecraft offering K3, P3 and W2 blank cases. This
could probably be done with little or no engineering effort on
Elecraft's part....just talk to the sheet metal vendor and have them do
the documentation. Maybe offer front and top panel options like a
speaker grill and ventilation slots for those that want to build
matching K3 speakers or a housing for their power supply.

Re: K-Line Addition - DC Power Supply (Suggestion)

The New Elecraft D3 power supply.

Features:

- Software defined power supply.
- Software upgrades via the web.
- Microprocessor controlled voltage and current meters with LED bar
graph.
- RS232 connection to K3 so you can monitor you current and power draw
with your PC.
- Automatically on/off via PC.
- DSP ripple filter to eliminate any ripple on the DC.

Coming soon the DX3 power supply for the KX3 and a new BX3 battery.

Sorry, I just could not help myself. I expect only the best from Elecraft,
so I can't imagine they would design a power supply without all the bells
and whistles.

Seems to me Elecraft already has a great linear DC supply: It's built into the
KPA500. Repackage it as a stand-alone, done.
