A transformer which incorporates the primary and secondary functions into a single winding, which is common to both input and output circuits, and is designed to change the relationship of volts and amperes between the entire winding and its taps. Includes multiple winding transformers of like design and items in which a variation of the turns ratio or inductive ratio of inductive coupling is accomplished by connection to fixed terminals. Also, includes items having a provision for mechanically changing the turns ratio in progressive increments, by means of a shaft, voltage taps, ratio adjuster, or devices of similar design. Excludes:transformer (1), power; transformer (1), pulse.

not established reliability indicator, 2.250 inches nominal body width, 4.125 inches nominal body length, single phase to single phase single component input-output phase relationship, 380.0 hertz minimum and 420.0 hertz maximum single component frequency rating
