Ultra High Efficiency Isolation Transformers

Foster Transformer Company has re-imagined the isolation transformer. Our new ultra high efficiency isolation transformers provide a slim profile ideal for panel mounting with full load efficiencies exceeding 97% and up to a 25% weight reduction compared with prior models. These are the isolation transformers you’ve wished someone would build. Foster has.

More than two years in development, Foster Transformer Company is pleased to introduce an entirely new line of high efficiency single phase isolation transformers. With full load efficiency ratings from 97% to more than 99% at full load, these transformers can be installed in sealed cabinets without overheating. Their profile has been optimized to allow thinner panel constructions, and leakage current to ground has been minimized to reduce shock hazard. Available input voltages include all common commercial voltages. Three transformers can be connected in a bank for three phase operation.

  • Input Voltages: 120, 208, 240, 277, 347, 415, 480, 600V, 50/60 Hz
  • Output Voltages: 120, 208, 240, 277V
  • Ratings of 1.0 – 25.0 kVAUp to 25% lighter than previous generation
