NuTone C907 Transformer

The NuTone C907 transformer is a 16 volt, 30VA transformer that powers up to 3 door chimes in one home. It features a thermal cut-off switch that is designed to shut off the door chime system in the event of excessive temperature. The C907 transformer also features a lock-mount or wall-mount for quick installation and is constructed to be long-lasting. 

This transformer can be used for the discontinued IM3003 and IM3303 systems.
