The T1630 is a 16-volt, 30-watt doorbell transfomer. These products are individually boxes and have a 2-year manufacturer’s warrant.

This product is used to power doorbells with selenoids, doorbells that are highly musical, or sytems that use 2 or more doors.  The extra wattage also comes in handy when you have a long run or doorbell bellwire.

If you only need a 10W doorbell transformer, we recommend the DH905 doorbell transfomer by Thomas and Betts

    This transformer is powerful enough to power two two-tone Heath-Zenith mechanical chimes. One star deducted because the screw to attach transformer to the electrical box didn’t have enough clearance for me. Not nearly as easy as the plastic nut my last transformer came with. But, the chimes sound great with this transformer, so overall I am pleased.

    I replaced my old doorbell and transformer. I bought this 30 watt transformer because it was recommended if the run of the doorbell wire was over 50 feet. I have no idea of the length of run of the doorbell wire, it may or may not be over 50 ft. – this transformer works great. For the few dollars more than the 10 watt transformer it was worth it.
