Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Brooke Clarke]

Hi Chris:

Yes.  Just looked on eBay and in under a minute found Item 231877388026.
11.1 V   6.6 AH with a label rate of 75C, but the eBay ad says 75C-150C.  So it will produce between 495 and 990 Amps.  
The stock connector is the EC5, which is needed for this kind of current. It's the connector used on the devices which 
used to be advertised as car starters, but now are sold as battery chargers.

You are correct about 9V batteries.  A 10A short is about 90 Watts.   But
have you seen the specs on a LiPo Battery?

I have a 18 volt nominal 8,000 mAH LiPo battery that is rated "40C".  This
battery is safe and within design limits to discharge at 40 x 8,000 mA.
Yes, taking 320 amps out of the battery is acceptable, the battery is
designed for that.

The battery can continuously supply 5.7 Kilowatts over 2 times more power
then can a standard AC mains wall outlet.  Of course at that rate it runs
out of power in roughly one minute.  But you can do a LOT in one minute.

When you short the leads you get a LOT more than 320 amps

A battery like that costs only about $50 today so they are available to
almost anyone who wants one.

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Bill Byrom]

Since I have met Charles in person a couple of times at his office in
Austin and used their microwave multiplied golden low phase noise
oscillators for a project and recommended Wenzel to others, I admit my
bias in favor of his projects.

I was going to comment earlier in this thread about the advantages of
Powerpole connectors and my bad experiences with old circular pin power
connectors from Molex and Amp, but decided to wait until the inevitable
storm of competing arguments blew over. I just finished wiring a
Powerpole connector to an Amplifier Research 144 MHz low noise preamp
tomorrow for use in Field Day this weekend for some satellite contacts
by a friend. He's also borrowing a big 100 AH 12V AGM battery from me,
so I added an inline fuseholder to a Powerpole standard ARES red/black
plug setup.

We should all remember that circuit protection, a proper fire
extinguisher, and safety goggles are important for fire and personal
(explosion) safety when initially connecting our new experimental
setups. Fuses or circuit breakers should always be used for connections
to batteries. Even small modern batteries can supply very high peak
currents, and in some cases you might not be there to handle the
emergency. My two personal stories are:

(1) A common 9V (NEDA1604 style) battery should never be left where it
might contact a metal short, and should never be left in a pocket. I
knew better, but temporarily slipped an alkaline 9V battery into a
trouser pocket, where it was shorted by my keys and became extremely hot
very rapidly. The peak current might reach 10 A (depending on the
battery chemistry and how it's shorted), so the battery heats up very
rapidly!

(2) When I was in high school (about 45 years ago) and still learning
how electrical and electronic stuff worked, I decided I needed to try
resistance soldering. This soldering technique was described in the
William Orr W6SAI Radio Handbook (unrelated to the ARRL  Handbook).  I
had some AWG 14 insulated wire and a surplus 2.5 V filament transformer
(rated for over 25 Amps, I'm sure). I found some old welding rods or
copper rods to apply the current to the joint being soldered. After
hooking it all up, I applied the rods to the joint and was surprised
when the copper wire used for my connections rapidly turned red hot and
fused, dropping molten copper onto the floor. I thought I understood
Ohm's Law and power dissipation in resistors, but obviously I didn't
have a practical understanding of the current handling capacity of the
wire. The wire acted as a fuse before the primary circuit fuse or mains
circuit breaker had a chance to trip.

Wes, Don,

I am quite surprised at the negative reaction to Anderson Power Pole 
connectors. I have found them the best DC connector out there. I have used them 
for a decade or two for all my DC feeds and have never had a problem: in my 
home lab, my car, even for my laptop charger. They are inexpensive, reliable, 
genderless (hermaphroditic) and easy to crimp. I use them for my 5V, 12V, 24V, 
and 48V supplies as well as my DC backup systems.

What on earth are you doing with them that causes them to disconnect? I mean, 
they are not meant for towing or lifting or rappelling. For critical 
applications there is a plastic gizmo that keeps them mated; or just use a 
square or figure 8 knot on the cables.

Get the "real ones" not the knock-off clones.  Better plastic and
better precision molding.   There are lots of cheap ones on eBay.

HobbyKing has the best prices for authentic, higher quality ones.
Still only 80 cents.

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[John Ackermann N8UR]

For what it's worth, I use PowerPoles extensively -- I use them for all 
my 12V distribution on ham gear as well as time-nuts stuff.  One great 
advantage of the genderless design is that you can use extension cables, 
breakout boxes, and other tools to solve lots of problems.


But they do lack as a chassis-mount connector.  I was looking for 
something inexpensive and reliable for 12V power on some rack enclosures 
I was building, and came upon a series of connectors that I really 
liked.  They are Conxall/Switchcraft "Mini-Con-X" series, available in a 
bunch of configurations from 2 to 8 or so pins.  I use a 2-pin version 
with solder-cup connectors that take up to 16 gauge wire.  The chassis 
version mounts in a 0.61 inch hole.


They're not throw-away cheap, but not unreasonable: the chassis 
connector (Conxall/Switchcraft 7382-2PG-300, DigiKey SC2130-ND) is $4.32 
quantity 1, and the matching in-line connector (Conxall/Switchcraft 
6382-2SG-3DC, DigiKey SC1893-ND) is $7.06 quantity 1.  I'm standardizing 
on these for any 12V project that goes into a box.  (If I do anything 
with 24V, I'll probably use a 3 or 4 pin version to avoid mis-plugging 
across the voltages.)

the polarity. Tamiya connectors from RC to Ham radio had a different

through several hundred at this point) you don't create a mismatch of male

connect things that shouldn't be connected if you are not careful.

The silver plated PPs also hold up better in wet environments.  PPs are
bulkier than some other hobby connectors, but for a connector that is
connected and disconnected frequently, the PPs work very well.

A safety factor the PPs have is that all contacts are covered.  There is no
exposed metal that could lead to a short. They have a audible and tactile
click when they are connected.  They can also be oriented in ways to
prevent plugging different voltages together.  They can also be very useful
in making large "bus" connectors, but are horribly bulky if something
smaller would do.

I'm not always a fan of chassis PPs on equipment (K3), and a short pigtale
from the equipment or a captive connector like the Molex is preferred to
then go to PP's. A command strip or other attachment on the equipment with
the power cable held to prevent disconnecting alleviates unplugging it
however.

As far as connectors pulling out is concerned:
use a cable clamp to strain relieve the connection.

Neutrik make a variant specifically created for power connections instead

listed for up to 250V AC.

Most important, the power and speaker connectors are NOT intermateable. 
The little tabs and notches are different.



In the movie biz, the 4 pin XLR is pretty standard for 12 and 24VDC 
battery packs. It's been almost 20 years, so I don't remember the pinout.


The 3 pin XLR is a pretty good sized pin that can take a lot of current. 
 The 4 pin is smaller, and the 5 pin is really pretty small.


The XLR is nice and rugged (although not waterproof, it can be made so), 
and it tolerates being driven over or stepped on, and it locks. The 
chassis mount is fairly small (not much bigger than a Anderson PP with 
chassis mount housing/bracketry)

One of the problems of power poles is they are expensive.  Not a
problem if you only need a few of them.   I've been buying DC

mobile robots  I robot does not need many but for every finish one
you've build maybe four breadboard systems and then you have the
battery charging systems and the cables that connect battery chargers
to power supplies. (LiPo battery charging is complex when you get into

Power poles are also rather bulky.  OK if the equipment is stationary
but not good for something that flies or drives around where weight
and volume matter a lot.

I've standardized on XT60 type connectors  These very compact and
rated for 60 amps continuous.  Much easier to assemble and they cost
about 80 cents per mating pair.They are common in the electric
power drone industry as battery connectors
the XT60 is easy to use because they don't come apart.  the metal pins
are permanently molded into the shell, you simply solder the wires on.
The shell is high temperate plastic and withstands even unskilled
soldering.

I did something stupid last might and assembled power distribution not
as designed with a mosfet switch and diode in backwards then connected
a high power density battery.  I had an open flame along an entire run
of #18 cable but finally the coper conductor failed (the metal

Good point and for hobby use (ie. Amateur radio, time nuts pursuits etc.) I can 
see this being a consideration.   

That being said in my prior day jobs where we had various solar panel, battery, 
charge controller, AC powered charger,  load combinations etc.. as far as I can 
recall I never encountered equipment that  allowed for that  specific use case 
via hermaphroditic connectors.  It is still a good point however.

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Magnus Danielson]

Hi,

The ITT Cannon XLR range became known as Cannon-connector and 
XLR-connector, with the later as the long term name. Often the 3-pole 
XLR connector is being used, but many other exists, including different 
sizes of pins and shells.


One should ba a bit careful to use the vendor name to identify a 
connector type.


BTW, I agree with Rick's comment on power-pole and use on batteries. 
This is the reason I use power-poles on my ham-equipment. It also allows 
for combining adapters in interestinng ways.


Cheers,
Magnus

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Richard (Rick) Karlquist]

No one has brought up the issue of hermaphrodicity, so
I will.  Only PP's are hermaphroditic.  Why does this
matter?  It matters in the case of a battery.  A battery
is both a power source and a power sink.  In the PP
system, you can make a 3 way connection between a
power source, a power sink, and a battery, where
the battery float charges on the 12V bus it is connected
to.  Non-hermaphroditic connector schemes do not allow
a 3 way connection.  Attempting to do a work around
would require fabricating a special 3 way harness,
which would not be idiot proof.

This is the fundamental reason for using PP's.

If you never use batteries, then all the other
gendered connector schemes are fair game.

As far as connectors pulling out is concerned:
use a cable clamp to strain relieve the connection.

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Mark Spencer]

For amateur radio use I've never perceived power poles as offering enough of an 
advantage over most other power connectors to make me willing to change my 
other connectors for power poles.  I do own some equipment that came with 
factory installed power pole connectors and I'm generally ok with how they 
work.   Some other amateur radio operators have expressed surprise at my 
extensive use of non power pole connectors and the use of power poles does seem 
common in the amateur radio world.

For time nuts and amateur radio use I've been quite happy with the multi pin 
circular "cannon" style connectors.  That would be my typical choice for a 
"high end" power connector for my various hobbies.  At the "low end" I'm happy 
with two pin "trailer" style connectors but in my experience they are generally 
only available in "pig tail" form.   Both the "cannon" style and "trailer" 
style connectors are readily available to me  as "over the counter" items which 
plays a major role in my affinity towards them.   

Where I used to work "Deutch" connectors were very popular and those are also 
available to me as an "over the counter" item.  I expect I'll start using those 
at some point as well and will probably switch out the bulk of my "trailer" 
style connectors for Detch connectors.

I can also see some merit in using XLR style connectors in some applications.   
I strongly dislike the use of "phono plugs" and PL259 connectors for power 
supply applications.  

All the best

Neutrik make a variant specifically created for power connections instead
of speaker connections.  I think they are essentially the same style
design but with different color coding to make them stand out from speaker
connections.  I don't know if the contact plating may be different, or the
spacing different so it can handle higher voltages. Ground mates first
before the two power pins (three pin instead of the four pin Speakon).  UL
listed for up to 250V AC.

http://www.neutrik.com/en/powercon-20a/



Speakon and Powercon cannot mate. This is intentional, so you don't feed 
your speaker 240 VAC which would burn the speaker up in most cases.

Same basic ideas thought, but re-applied.

Magnus

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Magnus Danielson]

Hi,

The Powerkon variant, which does not mate with Speakon, is what is good 
for AC, and found use in the medicine world, as it does not 
self-disconnect like IEC-outlets tend to do (yeah, I know about securing 
them and I've seen it missused many times but I made sure we have such 
securing on our products).


Speakon for power would however be useful for DC.

It used to be that speakers where connected using the XLR range of 
connectors (not only the 3 pin XLR connector, but larger sized 
variants). Those connectors can handle power and current nicely too, but 
there can be better choices and that's where the Speakon comes in for 
the speaker-feed, which got much handier.

Actually, I read it with interest. I am designing quite a bit of
electronics. A lot of it is single use, then "throw-away" these
days so long running times are not that much of an issue.
But selecting the right power connector is always a problem
I face. I often choose the 5.5x2.5mm barrel plugs, as they are
quite common on power supplies, but they are kind of suboptimal
when it comes to retentiony The Kycon 4-pole plug is slightly
better, but every and each power supply has a different pinout,
which means that I either need to design it for a specific power
supply or add 8 diodes to get the polarity right.

I pondered a couple of times to use Molex Micro-fit connectors,
as they are cheap, locking and available in almost any number of
poles. The current and voltage rating hare high enough for almost
all needs (but not enough for 240V mains, even if it's rated 300V!).
And incidentally the crimping tool doesn't cost an arm and a leg.
But it's not really a connector one wants to use to power a device
in a proper housing.

Reading on what other people are using and what advantages/disadvantages
the different power plugs have is quite interesting for me.

So, please keep it comming!

OK I was wrong...  Attila was right.  IF we are going to talk
alternatives and not simply bash PP cons, then I'm in.  Always up for a
bit of over-engineering.  

The speakon connectors are interesting...

Do you have a favorite series/model, Mike?

Right Tool for the Job. 

I use barrel connectors when I _want_ the cord to come out when the unit falls 
off the shelf rather than dangle by the power cable. 

Locking Molex, or, far better, locking AMP connections when I want the unit to 
hang by the cord when necessary. 

We've gone to 9 pin circular locking AMP connectors for rotors on our 2x /year 
ham radio contest set up on the mountain (take a look for W2SZ / MGEF). 
Waterproof (not water tight), sturdy, impossible to misalign. And 40' of cable 
can hang from one for a few minutes if need be.

 Actually, I read it with interest. I am designing quite a bit of
 electronics. A lot of it is single use, then "throw-away" these
 days so long running times are not that much of an issue.
 But selecting the right power connector is always a problem
 I face. I often choose the 5.5x2.5mm barrel plugs, as they are
 quite common on power supplies, but they are kind of suboptimal
 when it comes to retentiony The Kycon 4-pole plug is slightly
 better, but every and each power supply has a different pinout,
 which means that I either need to design it for a specific power
 supply or add 8 diodes to get the polarity right.
 
 I pondered a couple of times to use Molex Micro-fit connectors,
 as they are cheap, locking and available in almost any number of
 poles. The current and voltage rating hare high enough for almost
 all needs (but not enough for 240V mains, even if it's rated 300V!).
 And incidentally the crimping tool doesn't cost an arm and a leg.
 But it's not really a connector one wants to use to power a device
 in a proper housing.
 
 Reading on what other people are using and what advantages/disadvantages
 the different power plugs have is quite interesting for me.
 
 So, please keep it comming!

Hi

There are some really nice aircraft grade connectors that only cost about $250 
each (as in
$500 a pair)  that take care of all sorts of issues :)

For my money, Power Poles do just fine.

Heh, I was thinking just that when I typed it. They're almost inverted, the
pegs are on the plug and the slots are on the socket, the ones I've seen
aren't spiral slots, you have to fully engage the plug before you twist.

I like PowerPoles, I like barrel connections, as with so many things it's
all about the application, choose the one that works for you.

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Wes]

Hi Tom,

I said I use PPs but I don't really like them.  If you use a pair as a cable 
splice then yes, you can tie them together, but in the specific case I referred 
to, the connection on Elecraft radios, the mate is sticking out the back of a 
panel and it's impossible to knot the cable or use a zip tie.  I am certainly 
not the only one who has had issues with this.  And lest I be called an idiot, 
this is with a factory assembled and supplied pigtail.


Regards,

Wes

Locking barrel connectors...

Aren't those called BNCs? ;)

In one of my other lives, I see Power Poles used in a very life critical 
application. They are used to connect pads to Automatic External 
Defibrillators. In that application, the two poles (15A, red & white) are glued 
together rather than using the roll pin.

It is possible to get hold of locking barrel connectors, they insert as
normal and a quarter twist fastens them in place. The plugs and sockets are
compatible with non locking equivalents too.

Of course they're not great for applications that need a decent amount of
current and other disadvantages as noted elsewhere.

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)

[Tim Shoppa]

Whoops. Since Tom invited us to this off topic discussion, my two minor 
complaints about PowerPoles:

1: No make-first for ground. This is actually alleviated by other Anderson 
connector styles - in the 15A range they have a make first pin (which breaks 
the hermaphodicity). And in the big-boy multi hundred amp range they use a 
secondary make-last set of contacts to authorize application of power by the 
source.

Without a make first for ground you worry that some flimsy signal ground might 
be asked to carry 30Amps.

2: Not locking. Well at least we aren't going to be dangling a piece of 
equipment falling off edge of bench by the power pole.

Despite the above two caveats I don't have anything better. Molex connectors 
aren't really locking either and the certainly don't last at their rated 
current when exposed to an automotive or outdoor environment.

While the snap in plastic clips do a nice job of keeping them
mated, the roll pin hole in the connectors is also a perfect size for a 
4" zip tie, if you want to be /sure/ it doesn't go anywhere until you
let it.

I also have had good experiences with the PowerPole series; they
tend to stay put, are self cleaning, and genderless is a huge plus.  I
have seen more traditional DC coaxial connectors fall out than PPs.
And I've seen a lot more cracked Molex connectors, or Molex pins backed
out of housings.  As common DC connectors go, they're just fine, and a 
lot easier to work with than some of the newer alternatives.

They aren't idiot proof though.

I've seen them assembled backwards so that the contact occurred on the flat 
springs with predictable results.

Wes, Don,

I am quite surprised at the negative reaction to Anderson Power Pole 
connectors. I have found them the best DC connector out there. I have used them 
for a decade or two for all my DC feeds and have never had a problem: in my 
home lab, my car, even for my laptop charger. They are inexpensive, reliable, 
genderless (hermaphroditic) and easy to crimp. I use them for my 5V, 12V, 24V, 
and 48V supplies as well as my DC backup systems.

What on earth are you doing with them that causes them to disconnect? I mean, 
they are not meant for towing or lifting or rappelling. For critical 
applications there is a plastic gizmo that keeps them mated; or just use a 
square or figure 8 knot on the cables.
