DOE 2016 Efficient design reduces core and winding losses, delivering measurable energy savings in continuous operation. The business impact is lower operating costs and cooler plant rooms, which translates to reduced cooling load and improved equipment reliability. In practice, this transformer benefits manufacturing lines and data-center adjacencies where uptime and efficiency are non-negotiable. The 480 V primary to 208Y/120 V secondary configuration supports straightforward integration with standard plant power distributions, minimizing redesigns and enabling rapid deployment on existing circuits. Aluminum windings and a 220 °C insulation rating enhance durability in hot, industrial environments, contributing to longer service life and lower maintenance frequency. NEMA 1 enclosure and floor-mount design simplify indoor installation, allow compact footprint planning, and facilitate service access for routine checks. The +2 at 2.5% FCAN and -2 at 2.5% FCBN tap adjustments provide on-site voltage regulation to cope with short-term fluctuations without external equipment. UL Listed and DOE 2016 efficiency compliance reduce regulatory risk while supporting energy-performance reporting. The rugged GP framework (GPF) delivers a stable footprint that suits space-constrained electrical rooms and retrofit projects. Finally, compact documentation and the inclusion of standard specifications streamline procurement, permitting faster project approval and fewer vendor handoffs.

FAQs

When installing the N48D28F5516Q, prioritize a floor-mounted footprint in a clean, indoor location with adequate ventilation. Ensure an unobstructed NEMA 1 enclosure clearances and safe access for maintenance. Verify the 480 V primary and 208Y/120 V secondary terminations are correctly routed to the distribution panel, and plan for future tap adjustments (+2 at 2.5% FCAN, -2 at 2.5% FCBN).
DOE 2016 efficiency reduces core and winding losses, which lowers standby and running energy consumption. Over the life of the transformer, this translates to measurable reductions in utility bills and heat load. For facilities with continuous operation, the efficiency percentage compounds into a shorter payback period and improved regulatory alignment for energy reporting.
Yes. With a 500 kVA rating at 60 Hz and 480 V to 208Y/120 V outputs, it supports critical power distribution for manufacturing lines and data-center adjacencies. Aluminum windings offer good heat handling, and the NEMA 1 enclosure plus floor mounting simplify indoor deployment. Its voltage-tap capability helps accommodate short-term site voltage fluctuations common in busy industrial environments.
This transformer is UL Listed for safety, and it complies with DOE 2016 Efficient requirements and 10 CFR Part 431 documentation. These certifications support regulatory alignment, energy-performance verification, and easier procurement. Always confirm site-specific regulatory needs and maintain documentation for audits and facility energy reports.
Compatibility centers on floor-mount installation in indoor spaces with a NEMA 1 enclosure and 480 V to 208Y/120 V distribution. Regular maintenance should focus on terminating lugs, securing the enclosure, and verifying tap settings (+2 at 2.5% FCAN, -2 at 2.5% FCBN). Routine checks for insulation integrity and cleanliness help sustain performance and prolong service life.
