110 volt battery charging

I have a Ring Smart charger

Multistage charging at selectable max currents plus reconditioning stage and a final float/ maintenance stage.


The one in your link is not one of Rings Smartchargers

Why have they got 110 volts there?

Its a Scottish thing ... its cheaper, less than half the price of 240 volts :)

At the moment the charger is probably slightly smarter than the operator.

How clever are you with a screw driver and a couple of bits of flex? Have you got a voltmeter with you?

Will they imprison you if they catch you? How much of a near death exerience do you want?

If, what a wonderful word, they have used all 3 phases and you can find 2 different phases then you can get 220v. Usually given away by the different colour of the cables involved, but not always. But you should need yellow plugs not the blue ones for 230v - so you are probably stuffed anyway.

But you might get a shock or worse in the process and have to intimately examine more than one of the bollards to find different phases.

Or, you just run the inboard engine that you have probably removed in favour of an egg whisk in a hole in the cockpit.

The non existant engine needs to have an Adverc fitted to be of any meaningful use
 
That's true, but a quantum leap for the current level of technology.

Dylan ought to know that the Lidl chargers are cheaper and better, until the little push button thingie wear out.

More importantly that the lable saying 220 -240v or similar means something significant. Also Ring products and smart are not words often found in the same sentence.

But in fairness the Lidl do not work on 110v either - I think. I'll check next time I'm on board.

If it's a site-standard 110V supply it will actually be 55V two phase, and using a pin from another 3-phase colour will bring the voltage down. I'd draw the phasor diagram, but it's late and I'm tired. Basically, you can't draw a straight line between two points on a circle which is longer than the diameter.

Note: Site 110V is two-phase, from a centre tapped transformer, because there is never more than 55V to ground, and though 55V will give you a jolt it is unlikely to kill you. American domestic 110V is single-phase, which they double up to 220V two-phase for bigger stuff like cookers. People sometimes import American boats and use site transformers to feed them shore power, which is fine as long as you are quite sure you don't mine live and "neutral" both being 55V ac.

110V in a marina, that's a new one on me.

You need to either get a universal input charger, or a step up transformer.

Chances are most computer power supplies these days will be fine on 110V

it is a first for me... never come across one with 110 before

elfin safety I guess

as I have not yet bought a replacement battery charger can anyone recommend one that will work on 110volts

keepin g the boat here for a month is £120

keeping it in Inverness (with 240 volt and interwebble ) is £230

so I can invest in a battery charger but a step up transformer is

and I will never need it again

If you acquire a 12V/24V (non-smart) battery charger you can use it with either 110V or 220V input, just select 24V o/p with 110V i/p.
Because your i/p is halved so will your o/p.
Likely to be a higher Amp o/p so shouldn't be left powered for days without monitoring.

Old fashioned ones with a mains transformer inside maybe ............. but modern types I doubt.

but maybe you are an electrical engineer and know more about this than me ?

Staying here for the month and have found a socket I can use in the dinghy shed. So..... mostly this autumn I will be seen carrying a batteries back and forth between boat and dinghy shed.

However, Nairn is a really splendid place

any links for such a device anyone?

You could look at something like this
http://www.sealey.co.uk/PLPageBuild...tmicrogroup=&analysiscode=&requiredresults=16
or its' big brother
http://www.sealey.co.uk/PLPageBuild...tmicrogroup=&analysiscode=&requiredresults=16

or this http://www.screwfix.com/p/ring-rcbt30-30a-charger-and-jump-12-24v/37237

Truck auto electrical supplier will have alternatives perhaps as trucks commonly use 24V
You need a "thick as a plank" charger, not a "smart" charger
