Tailored For Your Specific Need

Our custom three-phase inductors are used in applications including aviation, power conditioning, renewable energy power conversion and high-power battery charging, to name a few.

Designs may incorporate foil and high-temperature windings, strip-wound amorphous metal, ferrite or high-grade steel cores. Dimensions and mountings are tailored to suit your specific need. Inductors can also be incorporated into the primary winding of a transformer to save both cost and space.
