FAQs
Designed for standard 480 V three-phase power systems with a 400Y/231 V secondary, this transformer uses copper windings and a 919X frame to fit common electrical rooms. It integrates with existing feeders and bus systems, supports typical mounting configurations, and is protected by WS35 weather shielding for outdoor or harsh indoor environments. Ensure clear ventilation and proper clearance for service access during installation.
The unit is a dedicated harmonic mitigating transformer with precise voltage taps (+2.5%, -2.5%) to maintain tight voltage regulation and reduce harmonic currents that can distort loads. This improves efficiency of downstream equipment, reduces linear distortion, and minimizes nuisance trips, especially in facilities with nonlinear loads such as drives and power converters.
Yes. The X48M34F33CUEENON is UL Listed and designed to meet NEMA TP-1 efficient standards. These certifications certify reliability and efficiency in demanding environments. Combined with copper windings and a robust 115°C rise rating, the transformer is well suited for continuous operation in regulated industrial settings.
Two taps at +2.5% and four taps at -2.5% provide selectable voltage regulation to compensate for supply fluctuations. Use +2.5% taps when supply voltage sags, and -2.5% taps when supply voltage rises, ensuring downstream equipment remains within tolerance. This capability helps maintain consistent performance for sensitive loads and minimizes unnecessary equipment stress.
With a rugged copper-wound design, 115°C rise rating, and UL/NEMA TP-1 compliance, maintenance intervals are predictable and downtime is minimized. The 300 kVA rating supports scalable growth, while harmonic mitigation reduces energy losses and equipment wear. Overall, this translates to lower lifecycle costs, reduced downtime, and improved asset reliability in mission-critical applications.
