FAQs
The X48M28F49CUEENON is a three-phase dry-type transformer designed for 480 V primary and 208Y/120 V secondary. Install following the 200X wiring convention, connect to the incoming 480 V bus, and wire the 208Y/120 V secondary to the distribution panels. Use the 918A frame, verify mounting clearance, and select the appropriate taps (+2.5% or -2.5%) under load to maintain stable voltage. Ensure compliance with local electrical codes and UL/NEMA TP-1 standards.
Yes. The unit is UL Listed and conforms to NEMA TP-1 standards, with notes indicating TP-1 efficiency. This ensures compliance for utility and commissioning processes, reduces procurement risk, and supports industry-recognized safety and performance criteria in industrial installations.
Best suited for facilities with harmonic-sensitive loads such as drives, PLCs, and power-intensive equipment. Typical applications include manufacturing lines, data centers, and critical electrical distribution panels requiring clean, regulated power. The 480 V to 208Y/120 V configuration and 60 Hz operation support integration with standard industrial power systems.
Harmonic mitigation reduces harmonic currents, improving power quality, lowering heat losses, and extending equipment life. This results in fewer nuisance trips, reduced maintenance, and improved efficiency across the plant. The transformer’s copper windings and precise taps enhance voltage stability under dynamic loads, supporting reliable operation of motors and sensitive electronics.
Plan for copper-wound windings, a 150 kVA rating, and a 115°C rise for thermal performance. Use the 200X wiring scheme and consider WS34 weather shield for outdoor or harsh environments. Schedule periodic insulation and winding checks, verify tap settings during load changes, and ensure ongoing compliance with UL and NEMA TP-1 requirements to maintain performance.
