FAQs
This transformer is a heavy, three-phase unit (2121 lb) with dimensions of 30.68 in by 62.18 in by 31.44 in, requiring suitable crane access and a solid foundation. Plan wiring with the 203X connection and coordinate with nearby switchgear. Its dry-type design simplifies on-site ventilation and reduces oil-handling requirements compared with liquid-filled units, easing safety and maintenance during installation.
Key specs include a 150 kVA rating, 480 V primary, 208Y/120 V secondary, 60 Hz operation, and a -30° phase shift. Copper windings and a dry-type construction contribute to high reliability and low loss. Tap changers offer +2.5% and -2.5% adjustment to maintain voltage under variable loads, supporting stable performance in non-linear systems.
Yes. The unit’s harmonic mitigation, tight voltage regulation, and 115 °C rise capability align with data center and manufacturing needs. UL Listed and NEMA TP-1 compliant design enhances protection for critical loads, while features like electrostatic shielding and WS34 weather shield improve reliability in demanding environments and retrofit scenarios.
The X48M28F49CUEETHR is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficient catalog notes. These certifications support electrical safety, efficiency, and performance benchmarks, simplify regulatory audits, and strengthen warranties and procurement approvals in regulated facilities and mission-critical installations.
The transformer carries a one-year warranty from installation or 18 months from shipment. Maintenance benefits include a dry-type copper-wound construction that reduces oil management needs and fire-safety concerns. ROI is realized through improved power quality, reduced motor and drive life-cycle costs, and fewer unplanned outages in high-harmonic environments.
