The World series triad chassis mount Toroidal Transformer provides efficient, compact and cool running. It is approved to UL 506 and CE IE C 61558-1 and 615 58-2-6 and is constructed with a class B (130C) rated insulation system. The toroidal transformer has minimal stray fields for quiet operation around sensitive circuits. The transformer consists dual primaries and dual secondaries which allows for flexibility in the input and output voltages. The primary and secondary are both electrically isolated from each other and from the core itself. It is available in sizes ranging from 25VA to 2500VA and are equipped with leads for connections.
