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.
Example Types of 3 Phase Inductors & Chokes:
Zig-Zag
High Current / High Frequency / High Voltage
Litz / Copper Foil Winding

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.
We create powerful solutions that work - with guaranteed results.
