FAQs
For proper installation, ensure the transformer is mounted in a ventilated enclosure with adequate clearance for heat dissipation. Verify 1‑phase input 277/120 VAC wiring and ensure secure, shielded connections to control devices. Use the provided mounting footprint in standard electrical panels to simplify integration with MCCs and PLC power rails. Follow Eaton installation guidance for safe, reliable operation.
Yes. The unit is designed for 1‑phase 277/120 VAC primary circuits and provides a low‑voltage secondary suitable for control circuitry and PLC power needs. Its encapsulated construction aids in safety and reliability in industrial environments, while the 0.75 kVA rating supports typical control panel loads without over-sizing.
Certification status for this model varies by region and order configuration. Contact Eaton to confirm CE, IP ratings, SIL requirements, and any country‑specific compliance. This approach helps ensure the transformer meets local electrical standards and safety regulations for your application and installation site.
Encapsulated transformers typically require minimal ongoing maintenance due to sealed construction that protects windings and insulation. Plan for periodic visual inspections of enclosure integrity, thermal performance checks during commissioning, and ensuring clean, dust‑free environments. Eaton components are designed for long service life, which helps reduce replacement cycles and downtime.
Replacing a larger, less efficient transformer with the S27N12P76P can reduce energy losses and heat within the control panel, lowering cooling loads and energy costs. The compact, encapsulated design also speeds installation and minimizes spare parts while maintaining reliable isolation for sensitive control circuits, contributing to improved uptime and lower total cost of ownership.
