230v to 12v???????

[Rod_5082702]

Does anyone know if there's anything on the market that converts 230v to 12v? (I don't mean the other way round, buy the way!)

Many Thanks.

Thanks, my good man.

if you need more, do a search for CB power supplies. they run on 12 volts and lots are available that let you run them on 230v

If you have a maplins near you, they stock them

Hello Rod,

As Steve says there are plenty of such devices called power supplies.

What is important is to ensure you choose the one with the right capacity to cope with the appliances you want to use.

Also check out Maplin electronics.

If you post a few more details of you application I could give more focused advice.

whoops that should read they run on mains and supply 12 volts (well 13.8 but thats another story)

Well, basically, I want to run the caravans existing 5 12v florecent lights and a submersable pump off the 240v power supply whilst I do up an old caravan. Possible?

 

[sparkes]

yes, but the best and cheapest way would be to use a battery and charge it while not in use. then you can use the battery on the caravan when it is complete.

Even a cheap battery will run 5 lights and a pump all day.

Hello rod,

Steves solution is perfectly good but there are alternatives. You will need about 10A @12Vdc to run all the items.

As for cost, look at

Item XM19V - about the same cost as a battery and charger!

Dont be put off by teh 13.8V, that is a common charging voltage.

You can pay a lot more for switchmode supplies, but they generalry have a greater current capcaity.

Best of luck.
