FAQs
The unit is designed for a 480 V primary and a 480Y/277 V secondary in a three-phase, 60 Hz configuration. It delivers reliable voltage regulation across industrial loads, supports scalable expansion, and integrates with standard 480 V distribution panels commonly used in manufacturing and data centers.
This transformer carries DOE 2016 Efficient performance, UL Listed certification, and 10 CFR Part 431 Efficient requirements. These certifications ensure energy efficiency, safety compliance, and regulatory alignment for procurement and installation in regulated facilities.
Installers should leverage the NEMA 2 enclosure for environmental protection and mount on floor or wall in upright orientation. The unit’s copper windings and 115 °C rise support consistent operation, while a shield and WS60 weathershield enhance EMI protection and outdoor readiness, reducing service interruptions.
K-Factor 13 indicates enhanced tolerance to nonlinear loading, minimizing core and winding losses under common non-sinusoidal conditions. This translates to cooler operation, better efficiency, and lower operational costs in systems with irregular load profiles, such as data centers and mixed-use facilities.
Energy efficiency from DOE 2016 compliance reduces operating costs, while copper windings and robust enclosure reduce maintenance and replacement frequency. The adjustable taps help maintain output under voltage fluctuations, and the shielded, weather-ready design minimizes ancillary protection costs in long-term deployments.
