Ultra-Efficient Transformers | Electronic Support Systems

Power Quality International (PQI) dry-type, distribution transformer. Provides ultra-efficient distribution. 480:120/208 VAC model.

Ultra-High Efficiency

Exceeds NEMA TP 1-2002 and CSA C802.2-12 efficiency requirements
Exceeds NEMA Premium® Efficiency Transformer Program qualification requirements
Exceeds pre-2016 [10 CFR §431.196 (a)(1)] and post- Jan 1, 2016 [10 CFR §431.196 (a)(2)] U.S. DOE efficiency legislation
Meets or exceeds previously proposed U.S. DOE efficiency legislation including Candidate Standard Level / Trial Standard Level (CSL/TSL) 3 or 4 efficiencies
Ultra-low Excitation (no-load) Losses provide high efficiency during periods of light-loading (<15% FL)
Significantly lower Impedance (load) Losses provide high efficiency, and reduce temperature rise and A/C loading during periods of heavier loading (>15% FL)
Peak efficiency can be matched to anticipated or measured average loading above 35% full load
