FAQs
Begin with confirming UL Listed and NEMA 3R suitability for outdoor panels. Mount the compact transformer securely, then connect the 120 V primary and 277 V secondary lines via the 519G wiring interface. Provide proper enclosure sealing, verify clearances for heat dissipation, and ensure voltage test after installation. Use standard 60 Hz power and observe weight limits during handling.
Ensure the unit matches your load with a 1 kVA rating at 60 Hz and is configured for 120 V primary and 277 V secondary. Confirm single-phase operation, 115 °C rise tolerance, aluminum coil construction, and UL Listed status. Verify enclosure rating (NEMA 3R) for indoor-outdoor use and that wiring connections (519G) are compatible with your panel design.
Yes. The 120 V to 277 V output supports lighting circuits and control loads commonly found in commercial spaces. The 1 kVA size accommodates medium lighting or mixed control loads, while the encapsulated design and UL safety certification help ensure reliable operation and compliance within distributed lighting bays and panels.
The S12N27S01 is UL Listed, indicating adherence to recognized safety standards for electrical equipment. It also features a NEMA 3R enclosure suitable for indoor-outdoor use, providing weather resistance and durability. These certifications help with procurement approvals, installation in regulated facilities, and long-term operating reliability.
The unit carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. Maintenance requirements are minimal due to encapsulated construction and robust enclosure. For service life optimization, ensure proper ventilation, avoid physical impacts, and perform periodic visual inspections of connections and enclosure seals.
