Needed this to power a gas fire pit, Codes requires Emergency electric shut off this supplies powder to that valve. By having emergency shut off 120V and the valve needed 24V. Perfect solution.

Product was easy to install as a replacement for an old furnace 24v transformer. Ready to mount on the existing box. Terminals are marked “C” for common, “R” for Load. 5 minutes to R&R. Tested and works fine.

My old transformer was only putting out 18 volts which would not run the doorbell and the new video doorbell (wireless chime). So I changed out the transformer and now it all works great. Lets see how long the transformer lasts, it should last a long time.

This is a good product. My dissatisfaction was the very slow shipping and delivery.

As of the time writing this, the product picture tells it all. The terminals on the low voltage side of the transformer (the "brown" side) are not marked in any way, so you don't know which one is for the Load. All the other low voltage transformers I have ever seen are marked, usually by a die stamp into the brown fiberboard with an "L", "LOAD", or "LINE". Not this one. I'm not an electrician and I didn't want to connect it wrong. I contacted Amazon support and we spoke on the phone and the agent was helpful - he didn't have an answer, but he was able to connect me with someone at Emerson, the manufacturer/importer. This gentleman wasn't able to help me either, but said an engineer would be available the next day and call me back. That didn't happen. I still don't have this information.

I used the transformer to power a new humidifier, instead of using the wall transformer. Power was taken from the HU terminal on the furnace control board. HU terminal is only active when the heat is on. Worked perfectly!
