Eaton S48N11B16PSS Encapsulated transformer - 1.5 kVA
Part Number: S48N11B16PSS
Quick Summary
The Eaton S48N11B16PSS encapsulated transformer provides dependable single-phase power for control panels. It helps engineers overcome enclosure protection challenges and installation uncertainty in demanding environments. Certifications should be confirmed with the manufacturer; verify CE, IP, or SIL status directly with Eaton as applicable. This device features copper windings, a compact EP design, and a 1.5 kVA rating, delivering reliable power with efficient operation. Note the Grade 304 stainless enclosure reference is for protection, not a formal NEMA 4X rating, and is suitable for indoor-outdoor use. With a 480 V primary and 120/240 V secondary output, it supports flexible installations and future panel upgrades.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature is encapsulated, copper-wound transformer design → Business impact is improved reliability and reduced maintenance in harsh environments → Application: control panels and automation racks requiring robust, long-life power conversion. Copper windings deliver higher efficiency and lower losses compared with alternatives, boosting overall system performance. This translates to measurable energy savings and cooler operating temperatures in demanding industrial settings. Feature 1.5 kVA rating → Business impact: accommodates typical control circuits and PLCs without oversizing → Application: machine automation in manufacturing lines, where consistent secondary voltages support precise motor and sensor operation. Feature 60 Hz single-phase operation with 480 V primary and 120/240 V secondary → Business impact: simplifies integration with common facility power and control circuits → Application: panel boards and sub-distribution in warehouses and processing facilities. Feature 68P frame and 524H wiring connection → Business impact: streamlined mounting and wiring compatibility → Application: compact enclosures and retrofit projects where space is at a premium. Feature indoor-outdoor weathershield and enclosure notes → Business impact: supports flexible deployments across indoor and sheltered outdoor installations → Application: gateway stations and equipment rooms with mixed environmental exposure. Warranty and service terms (25-000 policy) → Business impact: predictable support window and reduced total cost of ownership → Application: procurement planning and long-term asset management in facilities engineering. Note: Grade 304 stainless enclosure reference supports corrosion resistance but does not imply a NEMA 4X rating, so ensure site acceptance criteria are met during spec and installation.

FAQs
The S48N11B16PSS is a single-phase transformer with a 480 V primary and a 120/240 V secondary, designed for control panels and automation equipment. Its 60 Hz rating matches standard facility power, and its 1.5 kVA capacity suits PLCs, relays, and small drives. When planning integration, confirm wire sizing, enclosure space, and wiring method per 524H connection to ensure reliable operation and thermal comfort in the panel environment.
The 68P frame provides a compact footprint suitable for tighter panel layouts, while the 524H wiring connection standardizes how the secondary is wired to downstream equipment. Plan for proper mounting clearances and ensure the enclosure can accommodate the weight (21 lb) and any heat dissipation needs. Verify wiring diagrams in Eaton’s datasheet and use the specified connections to avoid performance issues.
The unit is rated Indoor-Outdoor and carries a Grade 304 stainless reference in catalog notes, which supports corrosion resistance in mixed environments. However, this note does not guarantee a NEMA 4X rating, so confirm site requirements and sealing needs with your facility standards. For outdoor installations, provide appropriate protection or enclosure enhancements per your hazardous area or weather exposure criteria.
Certifications are listed as 'Contact Manufacturer' in Eaton’s product data. For critical regulatory compliance such as CE, IP ratings, or SIL status, contact Eaton directly or reference the official specification sheet. Always document certification verification as part of your procurement and QA package to meet project and regulatory requirements.
Warranty follows Eaton Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This supports predictable maintenance planning and total cost of ownership. When evaluating ROI, consider reduced downtime, reliable power for PLCs and sensors, and lower retrofit risk thanks to a proven encapsulated design with copper windings and robust enclosure options.
