High-efficiency transformers

High-efficiency transformers are optimized to meet NEMA TP-1 limits, which specify maximum losses at an average calculated load of 35 percent of the nameplate rating. Compliance with the EPA Energy Star program allows U.S. customers to meet standards with E-versions of low-voltage, general-purpose transformers.

High-efficiency transformers are optimized to meet NEMA TP-1 limits, which specify maximum losses at an average calculated load of 35 percent of the nameplate rating. Compliance with the EPA Energy Star program allows U.S. customers to meet standards with E-versions of low-voltage, general-purpose transformers. Devices are available in single-phase voltages from 15 kVA to 167 kVA and three-phase voltages from 15 kVA to 500 kVA. (Sola/Hevi-Duty) Circle 27
