Triad Magnetics’ Chassis Mount World Series™ Toroidal power transformers are compact transformers that are both cost effective and highly efficient.
Approved to UL 506, CE IEC 61558-1, and CE IEC 615 58-2-6 standards, and constructed with a Class B rated insulation system, approved for operation up to 130ºC, our World Series™ Toroidal power transformers are highly versatile.
World Series™ Toroidal power transformers are manufactured with dual primary coils and dual secondary coils, allowing for a high degree of input and output voltage flexibility. The primary and secondary coils are electrically isolated from each other, and from the core, which helps to minimize stray electric fields and ensure quiet operation.
All of our more than 40 Chassis Mount World Series™ Toroidal power transformers, which range in electrical rating from 25 VA to 2,500 VA, are equipped with leads for each connection.

| Description | Triad chassis mount World Series Toroidal transformers are efficient, compact, cool running and cost effective. They are approved to UL 5085-1 and CE IE C 61558-1 and 615 58-2-6, and are constructed with a Class B (130C) rated insulation system. These toroidal transformers have minimal stray fields for quiet operation around sensitive circuits. The transformers consist 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 . Chassis mount Toroidal World Series transformers are available in sizes ranging from 25 VA to 2,500 VA and are equipped with leads for connections. | |||||||||
