K-Factor 13 nonlinear ventilated transformer design reduces harmonic losses and improves overall efficiency, translating to tangible energy savings and cooler operating temperatures in systems with distorted loads. Aluminum windings offer a lighter, cost-effective alternative to copper without compromising performance, helping with easier handling during installation and maintenance while supporting a 75 kVA three-phase capability. The NEMA 2 enclosure provides rugged protection against dust and moisture, reducing unplanned downtime in manufacturing floors and control rooms. DOE 2016 Efficient compliance aligns with regulatory requirements and may lower utility penalties or incentives while supporting sustainability reporting for facilities managers. Copper electrostatic shield addition enhances reliability in noisy electrical environments and helps meet EMI/EMC expectations in data centers and machine halls. Tap changes at +2.5% and -2.5% enable voltage stabilization under load swings, improving performance in environments with variable input or long feeders. WS60 weather shielding provides optional outdoor or semi-exposed installation flexibility, while the 208 V to 208Y/120 V secondary supports common panel and PLC architectures in industrial plants. Together these features deliver a dependable, energy-conscious transformer suitable for panel modernization, machine upgrades, and new builds with tight efficiency targets.
