Product Description Upgrade your doorbell and thermostat power with our 24VAC 40VA plug-in transformer. This transformer is the perfect solution to replace your old, insufficient power transformer and provide enough power for your thermostat and doorbell. Say goodbye to frequent battery replacements!

Specifications: Our transformer has an input voltage of 120 VAC, 60Hz and an output voltage of 24V, 40VA. The no-load output voltage measures at 26.6V, ensuring safe and stable operation. The transformer also features an auto-resetting (PTC) fused secondary and a green LED power indicator for your convenience.

Compatibility: This transformer is compatible with popular smart thermostats such as Honeywell, Nest, Ecobee, and Sensi. It can also be used with Video Doorbell, Video Doorbell 2, Video Doorbell Pro, and Nest Skybell Doorbell. Please note that the mentioned brands are only used for illustration of compatibility.

Easy Installation: The transformer is equipped with screw terminals for easy output connection. You can freely cut and arrange the connecting cable to achieve a clean and simple installation that suits your needs.

Multimeter Testing: When testing our products with a multimeter, it is important to use an AC voltmeter or multimeter to accurately measure the output voltage. For precise voltage output data, we recommend using a voltage tester. The no-load voltage output measured by the multimeter should fall within the range of 26.6-28V, which is considered normal and will not affect the performance of the transformer in any way.
