FAQs
The S27N11E07N is a single-phase transformer with a 277 V primary and a 120/240 V secondary. It operates at 60 Hz and is designed for indoor-outdoor applications with a 7.5 kVA rating, making it suitable for typical control panel and machine loads in industrial settings.
Yes. The unit utilizes a NEMA 3R enclosure and is rated for indoor-outdoor use, complemented by an electrostatically shielded design and UL Listed certification, which together support reliable operation across changing environmental conditions and simplify outdoor installations.
Key certifications include UL Listed and NEMA 3R enclosure compliance. The transformer is designed for 60 Hz single-phase operation and features an indoor-outdoor rating with electrostatic shielding, helping meet routine regulatory and EMI standards in industrial facilities.
A 7.5 kVA rating means the transformer can supply up to approximately 31.25 A on the 240 V secondary or about 62.5 A on the 120 V secondary (loads distributed accordingly). This enables powering multiple devices or a combination of controllers and actuators while maintaining safe thermal margins.
Maintenance is typically minimal due to the encapsulated construction and UL listing. Plan for regular verification of connections and enclosure integrity, and factor the 1-year (or 18-month shipment) warranty into ROI. The shielded design and rugged enclosure contribute to reduced downtime and predictable lifecycle costs in automated systems.
