The transformer uses a harmonic-mitigating design to improve power quality, reducing voltages and currents that can trip breakers or shorten equipment life, which translates to lower maintenance costs and higher plant uptime. This performance is critical for facilities with Variable Frequency Drives and other non-linear loads, where clean power translates directly into fewer product defects and less downtime. The copper windings offer excellent conductivity and thermal performance, enabling reliable operation at an 80 °C rise and reducing cooling energy when compared with alternative conductors. With a three-phase, 60 Hz configuration and a 480 V primary to 208Y/120 V secondary, installation aligns with standard industrial panels and minimizes wiring changes, while the taps at +2.5% and -2.5% support voltage matching for stable supply during fluctuations. The integrated electrostatic shielding and WS35 weather protection extend service life in harsh environments, enabling outdoor or semi-enclosed installations without sacrificing performance. Compliance features such as UL Listed and NEMA TP-1 certification ensure the unit meets critical regulatory requirements, simplifying project approval and commissioning. This transformer is a proven fit for data centers, manufacturing lines, and commercial facilities seeking reliable harmonic mitigation along with efficient operation and long-term ROI.
