Electromechanical autotransformer, designed to raise or reduce the mains voltage in order to supply the necessary voltage to
the equipment they are associated with. Three-phase, reversible multi-voltage supply.
The input and output voltages derive from a common winding (Class H 180ºC) without galvanic isolation
