Special Features:

Three variable autotransformer mechanically ganged and electrically connected in a wye. Primary power three phase, 440v, 60hz with intermittent plus or minus 30 percent transients of 1 second duration. The three units for three phase operation and the one unit for the single phase operation shall all be mechanically ganged to one drive. The unit shall be driven by a 115v AC induction motor. dimensions 24.125 in lg, 10.062 in. W, 9.500 in. H.

Properties:

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.
