Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)
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. http://www.prc68.com/I/PowerBankJumpStarter.html#Photos -- Have Fun, Brooke Clarke http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html Original Message 18 volt nominal 8,000 mAH LiPo battery ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)
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. > (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.

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)
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. -- Bill Byrom N5BB - Original message - From: Chris Albertson ...

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

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)
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)
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.

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

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

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

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

Re: [time-nuts] Anderson PowerPole (was Charles Wenzel GPSDO)
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)
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. --msa ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
