If you are in the HVAC business, this is the transformer to have. It is very well made and versatile, having a multi-tap primary. I have even used it as the first stage of a low voltage (5vdc) control system together with a full-wave bridge rectifier and the proper resistors. I have also paired them in situations where I needed more than the 40 VA supplied.

Our AC unit''s transformer died in the middle of summer, we hit 100 degree days most of June, July and August. There were no correct replacement parts available anywhere in our area, so we settled on a 20VA part to make due, but we knew we needed the correct size to keep it running. After researching the various parts available online, we selected this one based on cost alone since it had no reviews. It installed easily, with the same footprint as the OEM part and has kept our AC running cool and smooth. I would HIGHLY recommend using this part as a replacement thermostat transformer.

Not as beefy as the 30-year-old it replaced, but had the same good heft.

And inexcusably sloppy with the out wiring (3rd pic)... shouldn’t matter, but not what it could be.

We wouldn’t accept that in the USA manufacturing arena.

Unless you work for Chrysler... :D

The transformer went out in our heat pump sometime during the night, and being the weekend the appliance parts stores near me were closed. So I ordered this for same day delivery, and for the price was not disappointed, the wire colors were slightly different, but I followed the diagrams on both transformers and got it reinstalled and my heat back working by the evening! Thanks Amazon, saved me a ton of money vs calling a repairman. I installed the transformer and it is currently working in our split Ruud heat pump unit. I wiil update if I have any issues with longevity.

I must have gotten a defective unit. I thought I had the problem fixed, and the unit worked fine for about 25 minutes and then the whole system shut down. "Surely it can''t be the transformer again." Alas, when I ohmed the primary/120 side I got nothing. NO resistance. Secondary side was fine. The power source was clean, so I can only figure that I was unlucky and got a poorly constructed transformer. Actually, I should have spent the extra $3 to get the White - Rogers. I guess they''re not all the same. (Btw: it looked kind of cheap from the outset.) Good luck!

46VAC on the output side???
Reviewed in the United States on January 11, 2021
This fried my nice Ecobee thermostat. Luckily my control board tolerated the high voltage.
I''m used to a little variance.. but this was crazy. Wired black/white for 120 as a drop in replacement.

I now have a smelly burnt smart thermostat.
