INTERNATIONAL SERIES DUAL BOBBIN
MICROPROCESSOR TRANSFORMERS


International Series Dual Bobbin Microprocessor Transformers

  • Designed to meet UL, VDE, IEC and CSA.

  • Dual bobbin construction for low interwinding capacitance. Eliminates need for electro-static shielding and provides 4000V Hipot.


  • 130  degree C insulation system. Exceeds UL flammability requirement.

  • Dual 115V/230V primaries are standard.

  • DC Output combinations +-12V and 5V on +-15V and 5V. Rated at regulation output.
