The transformer was of decent quality but it arrived with one of the plastic housings that was broken. I attempted to return but it was not the same as other returns through amazon. I just kep the product and used it w the broken housing

Transformer failed 10 seconds after installation. It’s not rated at 240 volts primary input.

I hooked this up following the dubious diagram and after reading answers from the seller about the peculiar choice of color schemes and blew the damn thing...

This 24VAC transformer replaced one in my HVAC air handler that had a bad transformer. There was no 24VAC going to the thermostat to power it up. I replaced the transformer with this one and it worked perfectly. It's been installed now for about 2 months without any problems. Thanks again!!!
