Help to buy replacement power adaptor please !

[JohnW2]

Or try baring some 2.5mm twin and earth cable as a measurement gauge.

I would think that would not be too easy. The diameter of the L & N conductors in 2.5 mm² T+E is about 1.78 mm, so a fair bit of judgement would be required to use it as a guide when trying to distinguish between 2.1 mm and 2.5 mm (diameter) plugs/sockets.

I believe the pin is 5mm...

You already know that so long as the plug fits, the voltage is correct and the current capacity is equal to or greater than 1.2 amps then you are fine. What more are you looking for?

when you know nothing about electrics you panic and basically look for the same as the sticker on current label

it’s not easy to interpret for someone like me despite all the helpful advice

You believe wrong. That is the plug outside diameter.

You have been advised more than once regarding the current rating of the adapter.

Now you also know about the centre pin diameter, so you don't need to interpret anything more. Just determine the size of the centre pin and order the appropriate device.

The pin, is the pin size of the pin in the socket. They are specced by the outside sleeve size, plus the size of the pin which makes contact with the hole in the middle of the sleeve.

Now you need to look in the end of the plug, on the right in the picture and measure the size of the hole.
Or get a PSU with the multi adapter ends as previously suggested.

Hi all thanks for all the advice so far!

So sorry but this may change the requirement!!

apologies My dad didn’t explain his alarm unit properly

basically the power adapter has a wire - that has a female end I believe

this then splits into the Alarm panel and a transmitter - via a “Male”

so the power adapter I need to source has no pin! It has a female end connector :/

don’t think they sell this anywhere???

Sadly original Adaptor is not available supplier has confirmed

Any ideas?

Post picture of the psu and Gsm unit...

Pls see attached

This is what my new Adapter would need to plug into...

 

[sparkymarka]

Looks like an extender or a 2.1/2.5 adaptor...this should do ....

 

[Dave123456789]

Any idea why it has that battery pack laptop style bit in the middle?

 

[sparkymarka]

That’s the switch mode psu ....

How about this one then? 12v 2A. The 1200mA is a minimum, anything bigger is OK.
