Universal PDU Transformer

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.
