Furnace Power Supplies & Magnetics

Ideal for Optimizing Furnace Systems

Smaller in size and lighter weight, our water-cooled Power Supplies and Magnetics are used closer to the heat source (close-coupling) in the manufacturing of components for the Automotive, Crystal Growing, Aerospace, Medical and many other industries.

Increased Efficiency & Reduced Costs

Close-coupling improves energy efficiency, while substantially reducing energy, installation, operation and maintenance costs for various industrial heating systems such as; Atmosphere, Vacuum, Forging, etc.

Available in various voltages and frequencies, the size and capability of our Power Supplies and Magnetics can be designed to meet your application’s requirements. Our standard and custom magnetics include:

  • Single phase primary and secondary—single and multiple secondary windings
  • Three phase primary
    • Delta-Delta
    • Delta-Wye
    • Wye-Delta
    • Wye-Wye
    • Scott-T
    • etc.
  • Isolation and Auto type windings
  • Interphase
  • Multi-pulse
  • Step up and step down transformers
  • Frequency range of 4 to 2000 Hz
  • Primary and secondary Voltage ranges from 1 to 1500 Volts
