The ENERGY STAR program is aimed at reducing pollutants caused by the inefficient use of energy, while also making it easy for consumers to identify and purchase the most energy-efficient products. The ENERGY STAR program distinguishes UPS systems with efficiency ratings in the top 25% of the market. Qualified UPSs perform with excellence at 25, 50, 75, and 100% load levels, as verified by an independent certification body. By requiring consistent measurement methodology and the publication of test results, the ENERGY STAR program empowers consumers to make informed UPS comparisons.
