24V 40VA Thermostat and Doorbell Transformer, All Versions of Ring Doorbell

First I will say that the transformer works flawlessly as advertised. Immediately after getting it installed I knew as soon as I went to the front door to check the voltage on the doorbell that it was outputting the specified voltage. The light on my original doorbell was 10 times brighter that before. I did a voltage check anyway to confirm and it was 27 volts. That is expected and normal for this transformer while not under load. Under load it is 24v.Now, for the part I did not consider and one I would like to at least warn others about being a possibility. If you are getting this transformer, it is almost certainly because you are replacing an original anemic one that came with your older house. Mine was built in 92 and had a 10v 5va transformer. It was about half the size of this one. And of course, the people that built my house put the old transformer in a wall box behind the doorbell chime with all the wires stuffed in beside it. Well guess what? Yep. Im addition to violating code of not having high and low voltage wires running in the same box, this new transformer didn't come close to fitting in the same space as the original. Queue what should have been a 2 minute replacement job turning into a three day ordeal costing me an additional roughly 130 bucks and more than a fair share of frustration to completely reroute and rewire a wall and move the transformer into the attic. So, you know, just keep that possibility in mind. Hopefully the electricians that wired your house didn't do anything so stupid and it will just take you 2 minutes to replace.

One reason I selected this transformer was due to it having a UL label. The item was well packaged and appears to be well made. I had no issues with the installation and it provided the correct output voltage.

It's working very well . Thank you so much!!!

I returned it as I did not need it. Doorbell chime did not feed off of doorbell. Both are wireless.

This is the only one I found which is UL listed. Installed today and is working fine, powering a smart thermostat.This is a proper transformer so it is a bit heavy and takes up a bit of space. I had to get creative to find a good mounting spot but managed.

So this is what I was sent, an obviously returned item in a box sliced open exactly as the pic shows. Good thing it was in a shipping bag or I probably would have received an empty box. I’m not even wasting my time even trying this thing it’s going back. Couldn’t even bother to tape the box shut, sad

The checks my problem

Had problems with doorbell cam, then found out they need a larger output transformer then what I had! EASY install!

Encontré difícil dar con un proveedor en quien confiar, al menos este aparato llegó funcionando, había comprado otros pero no funcionaron.
