Espey developed this power distribution unit (PDU) for universal voltage inputs providing isolated power to global installations of conventional 380VAC, and 208VAC equipment. The transformer is capable of transforming a wide range of input voltages by off-circuit tap selection. Tapping is achieved quickly, and simply in the field via a custom high current tap-changer.
