DOE 2016 Compliant Energy Efficient Transformers

Motor Drive and KDongan’s 41, 42, 73 and 74 series products are designed to meet DOE Energy Efficiency guidelines established under EPACT 2016, which established energy conservation standards for certain types of general purpose transformers.

Features of 41, 42, 73 and 74 Series products include:

  • Meet NEMA DOE 2016 energy efficiency standards
  • Aluminum or copper windings
  • High quality, electrical grade core steel
  • 41 & 73 Series have a 220°C insulation system with a 150°C temperature rise
  • 42 & 74 Series are copper-wound, have a 200°C insulation system with a 150°C temperature rise
  • 60 Hz
  • Wound with electrostatic shields as standard
  • Standard enclosures meet NEMA Type 3R
  • Available wall mount brackets
  • Non-standard designs available
  • Vibration dampening pads
  • Available options:
    • Virtually any voltage combination up to 600 volts may be ordered as DOE 2016 compliant
    • Core and coil designs
    • Lower temperature rises of 80°C and 115°C are available
    • 10 year warranty

The following types of transformers are excluded from having to meet EPACT 2016 standards:

  • Autotransformers
  • Grounding
  • Machine Tool control
  • Motor Drive Isolation (except in Canada)
  • Non-ventilated
  • Rectifier
  • Regulating
  • Sealed
  • Special impedance
