FAQs
This transformer mitigates harmonics and stabilizes voltage in a 480 V to 208Y/120 V three-phase configuration, reducing distortion that can disrupt servers, storage arrays, and UPS systems. Copper windings, NEMA TP-1 efficiency, and secondary SPD protection deliver reliable power quality, while the 112.5 kVA rating supports mid-range loads common in data center edge installations.
The 112.5 kVA rating provides a solid mid-range distribution capacity suitable for critical load clusters and medium-sized branches. It enables clean power delivery to multiple cabinets or machines without oversizing, helping facilities manage upfront costs while preserving headroom for modest future growth.
Yes. The unit is UL Listed and NEMA TP-1 compliant, with design features such as a 115°C rise and an electrostatically shielded construction for robust performance in industrial environments, ensuring compliance with applicable electrical codes and safety standards.
Plan for indoor installation with adequate clearance and ventilation. The unit uses copper windings and a 200X wiring connection, with a rugged frame (Type 917) and dimensions around 24.67 in depth, 56.17 in height, and 31.44 in width. The WS34 Weathershield option and 60 Hz, three-phase configuration support standard facility layouts and quick retrofits.
Eaton’s policy provides a one-year warranty from installation or 18 months from shipment, whichever occurs first. For maintenance, follow standard transformer preventive schedules, monitor winding and insulation temperature, verify taps during voltage swings, and inspect secondary SPD indicators to sustain performance and uptime.
