The VPT230-2170 is a toroidal mount World Series™ Power Transformer provides an efficient, compact and cool running solution. 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. Built with Class B (130°) insulation system.
