Installed to run two UV lights in the HVAC air handler. Output voltage was a little high at 26.5 VAC but that is in the range for the ballasts running the UV lights using external power. No noise, no heat and it has its own breaker. I would recommend this product.

been in operation for about a year now, pushing two large contactors, inside a controls box out in a field.

Arrived with a broken circuit breaker reset button. No output despite manually holding the reset button in. Returning it for a refund.

I used two of these for gas control kits (Honeywell/Resideo Y8610U) that required 24 V, 3 A. The transformers worked fine.

my furnace had started acting up, short cycling the blower fan, on and off with only 5 seconds or so between switching, so i shut it down, popped the access panel open and noticed right away that the 24v transformer was warmer than it should be, so i just took a chance, ordered this replacement, 4 wires connected (don't need the red or orange for my application) and i'm back in business,. Easier, cheaper ,and maybe even faster than trying to get an HVAC pro in my house to do it!

This little transformer easily replaced the 30 year old transformer in my air handler. Seems to make everything run a lot smoother now, plus there's actual protection on the circuit so that it hopefully won't kill itself again.
