NOTE: DSC has ceased to make their own transformers. In an effort to help customers locate this transformer as needed we have opted to keep this part number active for the time being and simply provide an alternate transformer of the same specification as the DSC PTC1640 model.

DSC PTC1640 power transformer. 16.5 volts AC, 40 VA. For use with most all brands and models of alarm systems, including DSC, GE Caddx, Ademco and others. This model is an upgraded version of the DSC PTD1640.
