HQRP 120V-240V to 24V 40VA Transformer Compatible with Nest, Ecobee, Sensi, Honeywell Thermostat, Nest Doorbell and All Versions of Ring Doorbell Power Supply Adapter Door-Bell 120v-240v-to-24v, UL

I needed a "doorbell" 24v transformer to power a couple of water valves. They are inside so being waterproof was not an issue. This transformer with the mounting plate was perfect for the project. Easy to install after turning power off if you are comfortable working with electrical devices. The only thing I added to the 24v side was a fuse just in case.

Excellent replacement plate mount 24v/40AV transformer for burnham boiler. Easy to install since everything is labeled R and C, and wires connected are color coded, black and white for 120v power connection. It is also too cheap relative to the original burnham transformer price, which is also scarcely available! It corrected automatically c wire problem with my nest thermostat. Highly recommended for heat boiler.

Seems to work and provide the correct voltage. A little noisy until it tapped the bottom of it. My eufy hardwired doorbell camera chime works as well as the original doorbell now. The original didn't work when I installed the eufy doorbell camera, it does now after installing the transformer. Hopefully I don't have to tap it again to stop buzzing. If it didn't buzz I would have given it a 5 star.

The first from another company did not work after one use. This one is working great.

I purchased and installed the Transformer, and it works perfectly. The one I got is exactly as described and there were no problems.

I replaced my faulty hvac transformer with this and it worked like a champ. The photos and answered questions in the listing for wire connections were more helpful than the printed instructions. Regardless, it was straightforward and simple. A quick double check on my wiring after installing and then my HVAC was back on business in under an hour of delivery.
