High-efficiency harmonic mitigation starts with the core ratings of the X48M28B22CUEETHR: a 225 kVA, three-phase dry-type transformer with a 480 V primary and 208Y/120 V secondary rated for 60 Hz and an -30° phase shift. Copper windings minimize copper loss and ensure stable operation under peak loads, while an 80 °C rise specification keeps temperature rise within design limits in demanding environments. The 919X frame and 44.2 in width facilitate cabinet integration, and the Weathershield WS35 enclosure supports outdoor or harsh indoor settings. Tap-changing is built in with two taps at +2.5% and four at -2.5%, enabling precise voltage regulation to maintain downstream equipment performance. This combination reduces voltage excursion, prevents nuisance trips, and extends the life of drives and sensors in power-intensive applications. In addition, electrostatic shielding helps minimize EMI, supporting reliable control system operation across manufacturing lines. Copper windings, a robust enclosure, and precise taps make this a versatile choice for harmonics-prone facilities. Overall, the X48M28B22CUEETHR delivers measurable improvements in efficiency, compliance, and uptime in data centers, process facilities, and large commercial buildings.
