Custom Transformers


Chokes and Inductors

  • Wide range of custom single and three phase electromagnetic laminated transformers
  • Isolation transformers, autotransformers, electromagnetic reactors, pulse transformers, current transformers and ferro-resonant transformers
  • Low VA up to 100 kVA three phase
  • 50 Hz through 400 Hz
  • End-user applications: energy, transportation, medical, industrial controls, machine tools, automation machinery, power conditioning, audio equipment, power supplies, lighting, military/defense, electronics, OEMs
  • Efficient, smaller insize, lighter than a laminate transformer, less audible noise, lower stray emission level, lower operation temperature
  • Variety of mounting configurations
  • Many uses include power transformers, isolation, current, pulse transfomers and choke/inductors
  • Core types: tape wound silicon steel and amorphous materials, ferrite and powdered iron
  • 50 Hz to 500 kHz
  • .5" to 16" diameter
  • Height up to 8"
