FAQs
For installation, plan space for a floor- or wall-mounted unit with upright orientation, as specified by the NEMA 2 enclosure. Ensure adequate clearance for cooling, access to taps (+2.5% and -2.5%), and wiring accessibility for the 283B connection. Verify your ambient conditions meet the 220 °C insulation rating and that the site complies with DOE 2016 Efficient requirements.
Key specs include a 75 kVA rating, three-phase configuration, primary voltage of 480 V, secondary of 480Y/277 V, 60 Hz frequency, 150 °C rise, aluminum windings, and an electrostatic shield option. Tap settings provide +2.5% and -2.5% adjustment to maintain voltage under varying load and supply conditions.
Ideal for industrial facilities with harmonic-rich loads, such as automated manufacturing lines, packaging and process control systems, and data centers that require reliable power conditioning and voltage regulation. Its NEMA 2 enclosure, WS60 weather shield option, and shielded design also suit indoor spaces with dust or moisture exposure.
The transformer is UL Listed and complies with DOE 2016 Efficient standards, including 10 CFR Part 431 (2016) Efficient notes. These certifications help meet energy efficiency and safety requirements, simplify audit trails, and support procurement with confidence in regulatory alignment.
Benefits include energy efficiency savings from DOE 2016 compliance, reduced heat and cooling loads due to the ventilated design and aluminum windings, and a robust shielded configuration that minimizes insulation wear and electrical noise. With a durable NEMA 2 enclosure and modular tap options, ongoing maintenance is straightforward, supporting lower total cost of ownership.
