Re: [Elecraft] K3 PowerPole connector

[Bob McGraw K4TAX]

I suggest using automotive primary wire, #10 AWG for power cables.   It 
is stranded with much finer / smaller wire than THHN and is much more 
flexible than THHN.    It does correctly fit the 30 amp PowerPole 
connectors thus no splicing is needed or as suggested.


I also recommend not only correctly crimping the PowerPole pins but 
carefully flow solder into the sleeves.   Likewise on the other end, the 
correct size ring terminal should be used, crimped and soldered, for the 
power supply connections.


The transceiver power should come direct from the power supply, thus 
avoiding any DC distribution panels.

Bob, K4TAX

I use #10 all copper which just fits the 30 amp if you twist them really 
neatly. It takes several tries to where no strands get away.
We might warn folks about the copper clad aluminum that’s going around if you 
don’t read carefully.

Re: [Elecraft] K3 PowerPole connector - more info

[Rick WA6NHC]

I suggest that you also get Marine/RV wire as it is more flexible and 
easier to route neatly compared to the usual wire used (for the same 
size/rating).  Powerwerx may sell that, ask.


And that you go up one more size of wire to lower IR^2 loss, just because.

Re: [Elecraft] K3 PowerPole connector

[Don Wilhelm]

#10 or #8 wire will need the 45 amp contact blades.

However, if the purpose is to minimize voltage drop, there is no need to 
use the larger connector - construct the power pole with #12 wire about 
3 inches long.  Then splice onto that with #10 or #8 wire for the rest 
of the run to your power supply.

If the part that is built into the K3, I would strongly suggest  
getting the part direct from Elecraft.  These have to be securely  
mounted within the radio.


If the part that connects, note the following:

PowerPole connectors come in sizes according to the current amperage  
required for the particular circuit.


Anderson PowerPoles consist both of the red and black housing and the  
crimp connectors for the wires.


The housing size used in the K3 is the standard size that will fit  
both 15, 30 and 45 amp crimp connectors.   You choose the connector  
that fits the particular wire size.   30 amp capacity circuits are  
adequate to power the K3 and should be used.


Unless you purchase pre-assembled connectors you will also need a  
crimp tool to crimp the connectors to the wires.   There is also a  
small learning curve on how to crimp and insert the crimped wires into  
the housings.


I would get the parts you need from a company such as Powerwerx.  They  
can help with any connections.

Re: [Elecraft] K3 PowerPole connector

[Don Wilhelm]

Lee,

Unless you can be assured that they are genuine Anderson PowerPoles, I 
would hesitate to buy them.  Buy real ones and save yourself buyers 
remorse from inadequate contact area and the resulting voltage drop with 
higher current.


If they do not have a "A" embossed on the tip of the housing, they are 
not genuine.

[Elecraft] K3 Powerpole connector issue!

[VTuff59795]

Guys,
I built SN # 104 up in  about 4 hours to the 10 watt version (I have 
not yet fitted the 100 watt PA), it  went together so easily I was slightly 
disappointed that it was not more  involved!!! Joking aside the only (and I 
mean 
only) issue I have had was with  the main board mounted powerpole connectors!
 
When unwrapped the main PCB looked fine but upon assembly I noticed a  slight 
misalignment (around 0.75 mm) of the Red (positive) PP connector, it was  
shorter than the Black (negative) one! I nevertheless continued to build up the 
 
rig until it was completed then I noticed when connecting the power lead for  
initial testing that the mating up of the connectors was not very positive 
(i.e.  secure). Upon investigation I found that the internal metal connector 
was 
1.5 mm  short from being fully home in the board mounted housing!!!
 
Yesterday I partially dismantled the rig and removed both board mounted  
connectors and rebuilt them correctly. When reassembled everything was fine,  
this 
is the only issue I had with the kit but I must say that whoever fitted the  
Powerpole connectors on my main PCB should have had their arse (ass) kicked! 
The  wire was poorly tinned and badly aligned, still... It made it more of a 
kit for  me and let me use the soldering iron a bit more than intended so no 
harm done  ;-)

Vic:

IMHO, this is something that absolutely *should* be sent to 
[EMAIL PROTECTED] to make sure that the info gets to those who can 
do something about it.


Actually, I'm sort of hoping there be something like that on mine so I 
can generate some solder fumes :-).
