Designed To Withstand Demanding Environments

We build custom applications for many industries including the ones with tough, demanding Aviation and Marine environments. We know special consideration must be given to vibration, moisture, weight, contamination and qualification. Unique winding configurations, high-efficiency cores, high-strength and non-nutrient encapsulants.

That's why we work collaboratively with you and your technical personnel to to develop the optimal solution for your complex requirement.

Recent Work

  • Three-Phase AC Reactor - 3KVAR @ 400Hz (Model 216037)
    This AC Inductor is one of a family of parts designed for airport ground support test equipment. Used on a 400Hz, 208V line-line power system (120V line-neutral), this reactor is constructed using 10AWG rectangular magnet wire assembled on a specialty M2 electrical grade shunt steel core and non-magnetic aluminum brackets. Class H (180C) insulation system.
  • 3 Phase DC Differential Mode Power Inductor (Aviation Power)
    This custom three-phase DC power inductor is used in the Auxiliary Power Unit in a commercial aviation platform. 50uH, 125A/ph, 15kHz Tape-Wound E-Core, 0.010 Copper Foil Windings, High-Temperature Teflon Leads, Class H (220C) insulation. Insulation resistance, 40Mohm (min) @ 500Vdc. Manufactured in Canada.
