FAQs
Install in a ventilated dry location and connect the 480 V primary to the 200X wiring scheme with the 208Y/120 V secondary following the manufacturer’s diagrams. Ensure proper phase rotation and grounding, and verify taps at +2.5% and -2.5% during commissioning. Use UL Listed enclosure and respect NEMA TP-1 environments for reliability.
The unit is 45 kVA with a 480 V primary and 208Y/120 V secondary, configured for three-phase operation at 60 Hz. It features a phase shift of -15°, copper windings, and taps at +2.5% and -2.5% to adjust secondary voltage. It is designed as a dry-type transformer with NEMA TP-1 efficiency and UL listing.
Yes. Its 480 V primary and 208Y/120 V secondary output, combined with harmonic mitigation, improves power quality in PV inverters and industrial automation environments. The UL Listed and NEMA TP-1 efficient ratings support code compliance and energy efficiency in data-intensive facilities and solar-driven applications.
It is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficiency noted in catalog notes. These certifications support compliance in many industrial, commercial, and solar installations, and align with typical purchasing requirements for controlled environments and automated facilities.
The transformer reduces harmonic-related losses and voltage distortion, which lowers cooling and wear on connected equipment, potentially extending service life and reducing maintenance costs. Energy efficiency ratings plus robust cooling and shielding features help stabilize long-term operating costs and support predictable return on investment in automation-heavy environments.
