For Christmas lights - the original says on it:

In-Li Industries Co. Ltd
Model48. YL-20-24V
INPUT 230-240V ~50HZ
OUTPUT 24V~ Max 20VA

That should be easy enough, but the connector is similar to the kind
that some old stereos used for their speakers - a flat spade, next to a
round pin.

Any suggestions where I could find a suitable replacement?

Thanks,

Daniele

Cannot see the pictures on this page for some reason but there is a24v 20va
transformer listed:-
http://www.discount-christmas-decorations.co.uk/acatalog/Replacement-Transformers-For-Premier-Xmas-Lights.html
or use
http://tinyurl.com/3996u4m

Cut the DIN speaker socket off the old transformers and wire to the replacement?
Otherwise DIN speaker plugs and sockets available on Ebay (have not checked
Maplin).
Or cut the DIN plug off the lights and fit a standard (possibly 2.1mm) DC power
in-line plug to suit the new transformer.

24V 1.5A - " also includes a 2-pin mini-din socket, commonly used on
fibre-optic Christmas trees"

How similar? Could it actually be a DIN speaker plug?
http://www.maplin.co.uk/Module.aspx?ModuleNo=935

Maplin appear not to list a 2-pin *mini* DIN.

The plug is known as a DIN speaker plug and can still be bought from
Maplin, etc, if you can find a PS with the wrong one.
However, I've seen this connector used on low voltage lights before. Dunno
why - it's an awful device.

I have a couple of sets of lights using these, and confirm that it's a
DIN speaker plug & socket. I can only assume that they're trying to
use a different plug for each voltage, which is desirable if you're
plugging things in round the back of the sofa in the dark.

As far as the OP is concerned, I wonder whether it's really worth
getting a replacement -- from past experience the shops will soon be
cutting prices on unsold sets, if they haven't already.

These were the only attractive Christmas lights I've ever liked. The
only ones I see in the shops nowadays are huge, or blue.

Higher contact pressure than the concentric hollow plugs used for most
other low voltage supplies. For lighting currents, the hollow plugs
have a potential fire risk, especially if the plug is bent in the
socket so as to reduce the contact spring pressure even further.

It's also very cheap to assemble 2-pin DIN plugs on a moulding line,
as the terminals are easy to access before potting and can be done
automatically together on a bar soldering machine. Most concentric
plugs need to be hand-soldered.

Probably less hassle to cut the plug off and just solder them together
or use a bit of connector block.

Many Chinese makers are simply using the cheapest connector for the job,
with no attention paid to interchangeability and wrong voltage issues.
For example, many electro-bike battery packs are using an EU kettle plug
for charging - how effing stupid is that?

The connector is a DIN speaker pleg. Not the greatest..but usable.

You should be be to source a 24v or 2x12V mains transformer easily. get
one a bit bigger than you need wire it ip, construct a cardboard box
around it and POT the lot on potting epoxy or polyester.

Result will be a sealed safe 'brick'.

because its certified for moderate current low voltage use. I agree.
Vile devioce. when I designed an amp in the 70s, they wanted them. we
wanted screw terminals or clip terminals. WE ended up with both..

I don't think that's an actual supplier - I think that it's simply
reposting some content in order to appear in Google searches, for the

I guess that an adaptor described as:

INPUT: 230-240v AC 50Hz
OUTPUT: 24v AC 1200mA MAX: 28.8VA

would be a suitable replacement, is that correct?

If these are just AC transformers and aren't attempting to provide a DC
output, then I don't need to worry about their no-load/low/load
behaviour.

Because you could use a mains "kettle" lead to surprise the battery with
240V AC?

Any reason why a 2V DC output wouldn't be satisfactory (for the
Christmas lights that this thing will feed)?

Somebody somewhere will plug in mains to the battery pack, guaranteed.
Nice explosion and fire, iwt.
