Sorta on topic... 110V devices in 220V countries
I'm going over to Africa shortly to work on a project there.
I've been there before. Most of our small devices such as battery chargers, etc. all say clearly that they will run on 110V OR 220V sources so we generally have no problems. However... I now have around 30 small devices to plug in nightly and only two receptacles at our location. I haven't found a power strip that is rated for 110/220V yet - and even simple splitters aren't rated for that. I *think* a simple splitter (no surge protection, etc) should work but I'm curious if anyone has done such a thing? It's all about the wiring inside and these things are generally solid blocks of formed plastic with electrical connectors inside... Thoughts? Solutions? Random chastisements? The reason this is somewhat on topic is because we will be over there rebuilding a small village medical center. Our infrastructure is a steel shipping container that we have acquired. It will be modified to become a building of sorts. I'll also be gathering a water sample to test as their water there seems to have a strange issue. It comes out clear but within a little while, turns red in color. ...So while they do have a well, they don't have fresh water yet.

"Joe AutoDrill" fired this volley in
: I'll also be gathering a water sample to test as their water there seems to have a strange issue. It comes out clear but within a little while, turns red in color. ...So while they do have a well, they don't have fresh water yet. Certain iron/sulfur chemistries do weird-looking things when well water is exposed to oxygen. When untreated, my well water does this: If it's gently drawn down the side of the container with no splashing, all you see is clear water, with a sulfury smell. If you splash it violently or aerate it while filling (like with a spray nozzle on a hose) it comes out clear, stays that way for a few moments, then turns a dingy blackish grey -- almost like it's been inked, or a small amount of black latex paint had been added. Within 45 minutes, it again turns clear, and almost all of the sulfur smell is gone. Our water lab said it's simply and iron/sulfur reaction that is caused by changes in the amount of hydrogen sulfide gas as the aerated water "boils off" its H2S load. When I lived up on a limestone ridge in central Florida, we had heavy iron and calcium in our water, and it would turn a flocculent red in the toilets after exposure to air. LLoyd |

The only 240V rated power strips you will find will also have 220V receptacles, so you'd need plug adapters for everything. When I went to Egypt (north Africa) I just brought a normal non surge suppresser power strip and used a plug adapter on it. Everything I had to plug in was 100-240V auto ranging, so no issues there. I did test the power strip on 240V at home for a couple days before the trip to ensure no issues. If you have 30 devices to plug in, it would probably be worthwhile to build up a dedicated power strip bank into a nice Pelican case with a single power cord out of it, and perhaps a voltmeter included to monitor power quality. It would also be worthwhile to consolidate the wall warts and line lumps where possible, i.e. chop the power cords off all your 12VDC output supplies and wire them to a single 12VDC supply rated for the aggregate load of all the original supplies. Digi-Key has a huge selection of supplies to chose from for such a consolidation. I've done this type of consolidation many times with no issues. One supply for all 12VDC loads, one for all 5VDC loads, etc. Do the math and you may be able to find a multi-output supply on Digi-Key that can service all the loads. BTW, I'm a *big* fan of Pelican 1510 cases with the photo lid organizer add on. They are max airline carry-on size and basically indestructible so you can put all your expensive gear in them and keep them under your direct control at all times. People can slam the case around in the overhead all they want it it won't hurt it. |

I don't know about Africa. In China I would go into a store and shell out the Y50 or whatever to buy a 240V power strip (they have the dual outlets that accept the two-round-pin or the dual blade (without ground)). But there would still be a problem with the laptop chargers and other items that have grounds. As to what's available here.. I just opened up a good quality (Wiremold brand) power strip to have look-see. As you'd expect, the female 'connectors' are just bent strips of brass held in the molded housing. The bits of insulated wire are rated at 600V. That part will be fine. What would not be is the switch, which is rated at 120VAC and has a neon with a resistor suited for 120VAC. It will die quickly and may get very hot. The circuit breaker is also rated at 120VAC, so it won't be safe at 240V. That said, the thing _probably_ won't catch fire unless you overload it, so for AC adapters and so on (not hair dryers or other stuff that might tempt the CB to trip) it will _probably_ not kill you right away. It should go without saying that if you plug in a 120VAC surge suppressor-equipped strip into 240VAC you will have fireworks and bad smells as the Metal Oxide Varistor cooks. Maybe you'd be best to buy the strip over there and have enough plug adapters on hand to fit into whatever sockets they use in that country?

Here in UK our mains is 240V but most construction sites use 110V tools supplied from centre tapped transformers like these http://www.knighton-tools.co.uk/acat...nsformers.html The centre tapping means the highest voltage is 55 to earth so is much safer. The transformers are readily available and come in various outputs but they're heavy. Depends what VA you need. John |

At the moment, it is an aid thing... www.LifeForGhana.com is our site if it matters and I have links to all my personal photos on Facebook if anyone wants to see them again. (posted them last year) There is a TON of opportunity there for business though so my eyes and ears will be wide open when I go back this second time. -- Regards, Joe Agro, Jr. (800) 871-5022 01.908.542.0244 Automatic / Pneumatic Drills: http://www.AutoDrill.com Multiple Spindle Drills: http://www.Multi-Drill.com Production Tapping: http://Production-Tapping-Equipment.com/ Flagship Site: http://www.Drill-N-Tap.com VIDEOS: http://www.youtube.com/user/AutoDrill TWITTER: http://twitter.com/AutoDrill FACEBOOK: http://tinyurl.com/AutoDrill-Facebook V8013-R |

I suggest that you purchase a couple of 220/110 step-down transformers for
an additional level of line isolation safety protection, and then just use ordinary 120VAC power strips. This will simplify the power supply for everyone that's accustomed to 120VAC equipment. You can likely find a couple of the S-D-T units with on/off switches and circuit breaker protected outputs, to avoid needing any fuses, or the temptation to use improvised material for a fuse. Some of the Chinese/India electrical products are very low quality, so shop around here in the U.S. for some decent quality components.. durable, earth grounded, metal-cased power strips, etc are available if that suits you. I sometimes use 2 pieces of 3-blade to 2-blade polarized adapters (as risers) stacked together in power strips where a couple of 2-blade wall warts or sideways-type power adapters/chargers make utilization of the full number of receptacles impossible (very low power consumption devices only). Domestic U.S. electrical devices are typically designed with at least a 600VAC insulation rating. When you compare the insides of a 120V plug compared to a 240V plug, for example, the 240V contacts aren't separated by 2x the space. The established NEMA standards designate the specific pattern and orientation of plug blades to prevent 120V equipment from being plugged into 240V receptacles, and similar screwups such as 50A load into a 20A supply. Our 600VAC rated cable is used with both 120 and 240VAC circuits and power cords. Using NEMA-designated 120V components with higher voltages would be hazardous and confusing, so it shouldn't be attempted. I'm not saying that this was what you were suggesting, I just wanted to include that statement to clarify that I wasn't suggesting it either. -- WB .......... "Joe AutoDrill" wrote in message ...

You could easily package such a consolidated power package into a mid sized Pelican case and that power supply could be equipped with the native 240V plug properly. Putting such a package together should cost ~$200-$250 including the case. |

Even (good) desktop PCs don't have switches any more, which I would think is related to the power factor correction functionality. One thing that can help consolidate is to bring an AC-USB adapter with multiple ports, which can be used for charging all sorts of devices such as cell phones and MP3 players. Here's one that comes with the plug adapters and has 4 'outlets': http://www.amazon.com/Lenmar-ACUSB4-...66384&sr =1-2 Really, all I'm looking for are a few "recepticle multipliers" so...

It's an excellent idea and one I have in my "to do" file... but time is of the essence right now (leaving very soon!) and the finances are tight as we are bringing enough educational materials for a week's worth of "classes" for around 200 kids. That and a small construction project will make our luggage a "pick and choose what is most important" issue already. ....But I plan on doing something like that and shipping it in the next overseas container. -- Regards, Joe Agro, Jr. (800) 871-5022 01.908.542.0244 Automatic / Pneumatic Drills: http://www.AutoDrill.com Multiple Spindle Drills: http://www.Multi-Drill.com Production Tapping: http://Production-Tapping-Equipment.com/ Flagship Site: http://www.Drill-N-Tap.com VIDEOS: http://www.youtube.com/user/AutoDrill TWITTER: http://twitter.com/AutoDrill FACEBOOK: http://tinyurl.com/AutoDrill-Facebook V8013-R |

But what _ARE_ these "thirty devices?" Why do you need so much high-tech
in Africa, for heaven's sakes? About 1/3 of it is for communication. We are a team of 13 splitting up across a relatively wide area in the middle of *nowhere*. No plumbing, electrical service, fresh water or even farming... Just some seriously desperate people with a school house that is worse off than any condemned building I've been in.

Is it really red, or more orange? Our water has "clear water iron"` which
is clear (duh) until exposed to oxygen & the iron turns to rust. And then settles - it is actually particulate, not molecular. We remove it because of the staining, but it is perfectly safe.

Joe AutoDrill wrote: Did you read my suggestion about consolidating the devices? That is the most viable way to limit space and weight, and will generally give you a more reliable industrial power supply to replace a myriad of consumer wall warts and line lumps. You could easily package such a consolidated power package into a mid sized Pelican case and that power supply could be equipped with the native 240V plug properly. Putting such a package together should cost ~$200-$250 including the case. It's an excellent idea and one I have in my "to do" file... but time is of the essence right now (leaving very soon!) and the finances are tight as we are bringing enough educational materials for a week's worth of "classes" for around 200 kids. That and a small construction project will make our luggage a "pick and choose what is most important" issue already. ...But I plan on doing something like that and shipping it in the next overseas container. The last time I did this was consolidating power for four expensive Senheiser wireless mic receivers. It took a total of three days from reviewing the existing line lumps and ordering a suitable single supply from Digi-Key, two day shipping and an hour to chop the cords off the line lumps, wire to the new supply and test. |

a) Any of the switcher wallwart devices [aka "100-240V"] will be fine on 240. Your sole concern is plug conversion. If you can confirm that, i.e. be 100% sure no 120V only device will be along; then I might be talked into a hack solution, a 240 plug on a metal outlet strip w/120 receptacles. But I bet some luser plugs his 120-only something in when your back is turned, and it's history.... b) Many of the "travelers voltage converters" are garbage, and will destroy the device plugged into them. Some are crude diode choppers, others series resistors, etc. Incandescent lamps and hair driers are about the only safe loads. c) Any real transformer solution will be HEAVY for given watts of load.
