US voltage?

[mitt]

Generally 110v to 120v is acceptable and 208v to 240v is acceptable.  Nameplates say anything in that range.  If you were to put a meter in one of your receptacles it would probably read something like 117.4v for example.

I don't think 208 to 240 is acceptable.  208V is a specific application, not to be confused with 240V.

Yes, but 220 is wrong also.

120 is half of 240, which is target the utility is trying to hit at each house.

My local power utility has a range of 208-240V +/-5%
I have less than 200V 3phase at one of my main customer's location which uses a lot of power and the power company couldn't care less because it's within spec.

It amuses me to see considerably off voltages right within a substation.

You can have motors/loads that are designed for a lower voltage/higher amp draw within that range, but it still that range.  Unless you're thinking of 277V which is a leg of 460/480V and neutral, and is for specific applications.

For 208 it is +/- 5% and for 240 it is +/- 5%, but you can't have a 240V circuit running at 200V - that would not work for the attached loads and would be more like +/- 20%.  208 is a wye transformer rating and 240 is a delta transformer rating - both can give you 120V outlet circuits if use 1 phase on the 208 wye (very common in commercial), or if you center tap 1 phase of the delta, like houses around here are.

I dont know how it is in other countries, but as far as Residential is concerned,

most modern homes have a singel phase 60hz 220-240v comming in. Thats the target range. Its actually 2 lines of 120v comming in to your house, in the panels, there are 2 halfs. Each one takes a 120v.

So thats the set up in america. as far as 50-60hz is concerned, i dont think a DC charger is sensitive enough to care.
As long as you have 110-120v.

So you need a step down transformer with US receptacles.

For 208 it is +/- 5% and for 240 it is +/- 5% <snip>  

Got me there, although I do have a room of 15-30hp 240V motors running around 198-199V.

I'm hoping to get a GoPro camera when they offer it with the LCD screen option.

Where have you read they are offering a LCD Screen?

They just released a HD Version.

I wouldn't expect another version for at least a year unless I am missing something.

It is just semantics, but it is 1 phase of 240V delta coming into a house with a center tap so you can get a +120V and -120V on each half of the panel.

..............
  So you're saying your small appliances in your house and your country like an alarm clock for example are 220v?

Yes.

Just plug shit in until it works.  

That was standard MO in younger years.

As far as I can see on the internet, that's correct. Not something any shop carries, but available. The fun begins when I go to another European country with different sockets. That's easy enough to buy, but will take up room in my bags.

It's available "late spring" this year. Choice of larger battery or LCD which connects as a larger back lid on the latest HD models. It's in their online catalogue. Affordable too.

[1KDS]

Yes.

Wow, didn't know that.  I guess you'll need to step it down.  Frequency probably won't matter.

[JEFF_H]

Yeah? Are you gonna make it all 220?
Yeah. 220... 221, whatever it takes.

Did you contact the company to see if they will have plans for a 240V (or an auto-switching) wall charger?  The transformer will take more space and be heavier than the plug converters.  You can get a "universal" plug converter that is quite small.

hahaha, "late spring"

In GoPro years that is like 12 months.
