The EI480 three phase isolation transformer is a dry-type, air-cooled power transformer built for industrial voltage conversion between 480V and 240V systems. Housed in a fully enclosed powder-coated steel cabinet with a hinged access door, it delivers reliable galvanic isolation, noise suppression and equipment protection in demanding factory environments. Every unit is manufactured to order, so the capacity, voltage taps and terminal layout can be matched exactly to your application.
