Products

K-factor rated transformers are designed to meet the non-linear load demands caused by computers and other modern electronic equipment. These types of loads can cause severe overheating in distribution transformers designed to meet the needs of a pre-electronic era. The Jefferson line of non-linear transformers provides safe and efficient operation in non-linear load environments.

  • 15 – 750 kVA (some restrictions on larger kVA units)

Applications

  • For electronic load demands caused by modern office equipment
  • For indoor/outdoor applications
