LOW PROFILE SPLIT BOBBIN
PRINTED CIRCUIT POWER TRANSFORMERS

Low Profile Split Bobbin Printed Circuit Power Transformers


  • Designed and constructed to meet UL and CSA safety standards.

  • Low profile - allows closer printed circuit board stacking.

  • Split bobbin construction – center flange insulation barrier provides 2500 VRMs Hipot – non-concentric coil winding results in low interwinding capacitance, eliminates need for electro-static shielding.
  • Class S (130 C) insulation system.

  • Single 115V and Dual 115V/230V primaries are standard.

  • Dual secondaries for variety of utilization.

  • 12 pin bobbin design increases available options for multi-winding special orders.

  • Low regulation.
