Energy efficiency and compliance with DOE 2016 minimize operating costs and regulatory risk for continuous production lines. The transformer delivers consistent voltage regulation under nonlinear loads, reducing losses and improving equipment uptime for critical manufacturing processes. Copper windings and 220 °C insulation enable sustained performance in elevated temperature environments, extending service life and lowering maintenance costs. The NEMA 2 enclosure provides rugged protection in dusty or damp factory areas, while floor or wall mounting offers flexible installation for space-constrained facilities. A 2 at +2.5% and 4 at -2.5% tap changer supports precise voltage adjustments, improving motor performance and reducing thermal stress on downstream equipment. Three-phase 75 kVA rating with shielded construction and WS60 protection ensures reliability in demanding power-distribution applications.

FAQs
For factory floors, plan floor or wall mounting with upright orientation as specified. The NEMA 2 enclosure provides dust and moisture resistance, and the unit’s 31.5 in depth, 51 in height, and 34.5 in width help determine space needs. Ensure accessible wiring connections (889I) and proper clearance for cooling and maintenance access.
K-Factor 13 indicates enhanced tolerance to nonlinear harmonic loading, reducing losses and preventing overheating under pulsed or distorted currents. This improves overall efficiency, extends transformer life, and stabilizes voltage across non-sinusoidal loads common in modern drives and automated equipment.
Yes. The transformer complies with DOE 2016 Efficient standards, helping meet energy performance requirements while maintaining cost-effective operation. It is UL Listed, providing a recognized safety certification for electrical assemblies installed in industrial facilities and ensuring alignment with industry quality and safety expectations.
Primary voltage is 480Y/277 V and secondary voltage is 208Y/120 V, enabling compatibility with common industrial power networks and office/processing loads. This makes the unit suitable for retrofits where existing gear runs at 480 Y/277 V or 208 Y/120 V, allowing voltage conversion without major inverter or cabinet changes.
Schedule regular inspections of copper windings, insulation (220 °C rating), and cooling pathways to prevent overheating. The shielded design and electrostatic shield modification help mitigate EMI and prolong life. The DOE 2016 efficiency reduces energy waste, contributing to lower operating costs and faster return on investment in industrial automation projects.
