When equipped with enclosures, these transformers are installed in commercial, educational and government facilities as well as in industrial plants, office buildings, hospitals, hotels and data centers. They can also support renovations, upgrades and modernization efforts, or any new projects requiring voltage conversion compliant with local and state regulations. NEMA TP1-­‐2002/DOE CSL-­‐1, Energy Star rated transformers, 15KVA and above @ 600V or less, are specifically designed with the intent of providing reduced cost of ownership by being optimally designed for energy efficiency. These transformers can yield considerable energy savings over their functional lifespan and meet the requirements of the Energy Policy and Conservation Act of 2005 under Federal Code 10 CFR part 431. This act applies to all such transformers put into service within the United States after January 1st of 2007. Features: •
