noob querying ac adaptor replacement

[malcster1975]

sorry for the noob question but i think maplins are taking the p155 with the price they quoted me

i have a fibre optic star ceiling that i have mounted on a panel on the wall in my soon to born daughters nursey

the lead is not long enough by about 10" and in the past i have simply extended these but this time the cable is a round on so i dont fancy doing that (not confident enough )

i popped into maplins during my dinner break and the spotty oik behind the counter told me it would be £29.99 for an adaptor

on the back of my existing it reads
input 110/240VAC 1.0A 50/60Hz

Output 12V (i think its the dc symbol the line with 3 dashes underneath)
then 1A Max

am i right in thinking that i just need to match output amperage

the guy in maplins was trying to sell me a all singing all dancing multi plug thing


sorry if this seems a daft question but i work in a timber yard and supply and build with wood i have no experience with electrics

Kind regards
Malcolm

Are you talking about the lead from the output of the power adaptor to the lights? If so, does it have some sort of plug on one end of it? If it does, you may well be able to get hold of a cheap 'plug-in' extension for it.

Kind Regards, John

yes sorry my initital post was not complete its the adaptor from the mains to the control box

i added some pictures if it helps explain what i mean

Yes you just need to match
- voltage
- current (or greater)
- polarity (see the graphic to the left of the CE mark)
- plug.

Beware that there are a few similar-looking plugs that are actually slightly different sizes, both in internal and external diameters; in particular the 2.1mm vs 2.5mm internal diameter is hard to distinguish. The wrong one can seem to fit but not work reliably. Do you have a micrometer or calipers? Otherwise it's not easy to measure the internal diameter.

No doubt ebay could supply something cheaper than Maplin. What they were offering probably is the best that they stock though.

Or get an extension. Again I'd start with ebay:

As John said above, you should be able to get an extension but there is no standard size for the plug. You will need to measure (preferably with a micrometer) the diameter of the plug, and the diameter of the pin which goes into the plug then find an extension to match. As an example this one is 2.1mm internal and 5.5mm external http://www.ebay.co.uk/itm/1-5m-DC-J...for-CCTV-/291155711375?_trksid=p2054897.l5662

Edit - Beaten again

thank you

i am looking at an extension on amazon now

In that case, as I said, you ought to be able to get hold of a plug-in extension. Your problem is that those sort of plugs come in all sorts of sizes (both internal and external diameters vary). Although eBay would undoubtedly be a cheaper source, it may be easier/safer to take your plug into a shop (like Maplins) to make sure you're getting the right thing - or you could be brave, do some measuring and try your luck on eBay!

Kind Regards, John
Edit: I think we all beat each other this time

thank you everyone for the answers

and "thanks" given as well

Regulated power supply adaptor.
Model: Delta ADP-12EB.
Input: 200-240V, 0.5A, 50-60Hz.
DC Output: 12V 1.0A, Max.12W.
UK plug. Round tip connector, 5.5 mm / 2.1mm

assuming the plug size is correct (off to find my caliper) this is suitable ???

Yes (assuming it is 'reputable' and not a fake!!) - although, as has been said, the plug size is the $64,000 question, and the inner diameter can be very difficult to measure, even with a caliper (you probably need to find something which just fits into the hole, and then measure that).

I take it that the lead of this one is long enough?

Kind Regards, John
