DOE 2016 efficient design minimizes core and winding losses, reducing operating energy costs for solar projects. This translates to lower total cost of ownership in utility-scale installations and on-site power distribution. Copper windings and 60 Hz operation ensure reliable performance under variable solar input, with a 45 kVA three-phase rating that supports mid-range loads from 480 V delta to 208Y/120 V. Voltage regulation is enhanced by taps: 2 AT +2.5% FCAN and 4 AT -2.5% FCBN, enabling precise secondary voltage under fluctuating input to protect sensitive downstream equipment. The rugged enclosure and electrical construction—NEMA 2, FR940 frame, 220 °C insulation, and a 150 °C rise—allow indoor or outdoor installation in challenging environments, while WS58 Weathershield provides additional weather protection. UL Listed, DOE 2016 Efficient, and 10 CFR Part 431 notes support procurement, audits, and energy program reporting. Finally, compact footprint with measured dimensions supports space planning in mechanical rooms and outdoor enclosures.

FAQs
This transformer requires a stable mounting base with clearances for cooling and service access. Key dimensions are 21.13 in long, 36.88 in high, and 24.88 in wide, with an approximate weight of 505 lb. Plan for vibration isolation and sufficient elbow room for terminations and access to taps. Pad or base mounting is typical in outdoor or utility rooms, and ensure proper ventilation and protective enclosures as required by local codes.
The unit features a 480 V delta primary and a 208Y/120 V secondary. Tap settings include 2 AT +2.5% FCAN and 4 AT -2.5% FCBN, enabling ±2.5% voltage adjustments to stabilize secondary voltage under input fluctuation. Use taps to maintain voltage within tolerance for critical loads, reducing nuisance tripping and improving equipment life.
Yes. It uses a NEMA 2 enclosure and WS58 weather shielding for robust outdoor protection. Rated for 60 Hz operation with a 150 °C rise and 220 °C insulation, it is designed for harsh environments typical of solar deployment sites, mechanical rooms, and utility distributed generation installations.
The transformer is UL Listed and DOE 2016 Efficient, with 10 CFR Part 431 (2016) Efficient catalog notes, which support energy program reporting and procurement compliance. These certifications help ensure safety, energy performance, and regulatory alignment for utility and commercial solar projects.
Expect improved energy efficiency from DOE 2016 compliance, reduced copper losses due to copper windings, and reliable voltage regulation through selectable taps. The 45 kVA rating supports mid-range solar loads with 480 V input and 208Y/120 V output, contributing to lower operating costs, reduced downtime, and easier integration with existing distribution networks.
