SIGA design and manufacture a wide range of transformers for the medical industry. 

These can be supplied on either a stand alone unit or for assembly in customer’s equipment.

Medical Isolating transformers can be designed to meet client’s specific requirements, either toroidal or bobbin wound, and supplied either as the transformer only or assembled in a case.

Two standard models are also available, usually from stock – 750VA and 2000VA rating.

The specification for these is shown in the tables below:
