Transformer/adapter help please

[911 Rod]

My wife has a little tree with lights that she likes and the AC/DC adapter is broken.
I cannot find anything that goes down to 24V 0.1A.
Can a different amperage be used? Maybe 12V 1.0A?
This kind of electrical is not my thing.



After me searching and finding nothing, she goes to Home Depot and the guy there sells her these plugs. lol The guy was adamant that they would work. He needs to be moved to the garden center.

Just get the voltage right and an amperage as high or higher will be fine. It will only use what it needs. It is just a maximum rating.

[red-beard]

Fint is correct, it will only use what it is rated for. The rating on the transformer is the MAXIMUM load.

That voltage is the same as a door bell transformer. And those are available at home depot.

$15

24v doorbell transformer will work.

Thank you gents!!
I'll see what I can find in 24 volts

Put a .5 amp fuse on that doorbell transformer output. your home insurance company will appreciate it.

Assuming that your plug is just physically broken and still works, some epoxy would fix that as well.

That's what I did last time and when my 1 1/2 year old grandson pulled it off the wall it broke again. Grandma says no more glue. lol

Most of the doorbell transformers don't have a plug. Won't look very nice in the living room.

Are there screw lugs on the bottom of the transformer? What type of cable/connection runs from it to the tree decoration?

It's a table top tree and the wire comes from the tree and a plug (black) goes into the transformer.
Transformer is a glued unit without any screws.

Low amperage is probably due to the use of LED. Higher current will fry LED's without a resistor

These are not LED. The new ones are LED and are too bright, hence trying to keep this one going.

Rod, search Amazon for 24vdc wall adapters and they’re like $10 and you shouldn’t have to mess with the connector end. Best Buy used to have them as well. It’s a very common PS. As has been mentioned just make sure the Amp rating is over what yours is though I’d be very surprised if you actually found one lower than 100mA

[70SATMan]

They also carry adapter kits for various DC ends. The lower current rating on your transformer has nothing to do with it being LED or not… the load will pull what it needs. Just because one uses a transformer that can supply more current doesn’t mean that a LED load will be blown by hooking it up.

This comment worries me. Is there a safety hazard?

Using that transformer?? IMO, yes. It’s meant for a high current draw and if you short it,,,,, I wouldn’t recommend that for what you’re doing if your original picture is of the transformer you are trying to replace.

Regular low current wall adapters have built in limiting. That’s why they are not externally fused.

This should work?

Original looks like it has AC output.

Maybe, but that's DC. Depends on the tree electronics.

[stevej37]

I'm confused...I read most of the comments.

The tree will only light when someone presses the door-bell??

Could catch.
