By exceeding the DOE 2016 minimum efficiency standard, the U.S. Department of Energy quantifies the energy savings potential from more efficient transformers to be in the billions of dollars.
Furthermore, the U.S. Department of Energy states that lifecycle savings can be maximized by optimizing for real-world loading.
Most manufacturers have designed their low-voltage transformers to just meet the U. S. Department Minimum Transformer Efficiency Law (DOE 2016), setting the minimum efficiency at a single required 35% load point, under an ideal sine wave factory test profile, sacrificing performance elsewhere.
Powersmiths OPAL™ designed transformers enables customers to maximize efficiency, and obtain the full lifecycle savings potential – backed by real-world performance verification and a standard 32-year warranty.
