Feature → Business Impact → Application: The S20N11P16PSS delivers a reliable 1.5 kVA single-phase supply with a 240/480 V primary and 120/240 V secondary. This fixed turns ratio simplifies control-panel power design, reduces wiring complexity, and ensures stable voltages for sensitive automation devices, improving startup reliability and minimizing nuisance tripping in production lines. Feature → Business Impact → Application: Aluminum windings paired with EP encapsulation improve heat dissipation and insulation integrity, lowering thermal stress and leakage paths. In real-world plants this means longer transformer life, lower maintenance intervals, and more predictable performance in high-temperature switchgear and automation cabinets. Feature → Business Impact → Application: The enclosure family features a NEMA 3R indoor-outdoor rating and a Grade 304 stainless steel construction for corrosion resistance. This combination reduces field corrosion costs, simplifies outdoor installations, and supports compliant installations in damp workshop areas or sheltered outdoor locations. Feature → Business Impact → Application: The compact footprint (6.56 in L x 5.53 in W x 13.03 in H), 345 lb weight, and 67P frame align with standard mounting practices and common cabinet depths, easing retrofit projects and new builds alike. A straightforward 3A wiring connection minimizes field wiring errors and speeds commissioning. Feature → Business Impact → Application: UL Listed certification and Eaton warranty policy deliver regulatory assurance and predictable service life, helping manufacturers justify the capital investment, reduce downtime, and lower total cost of ownership through fewer replacements and faster maintenance cycles.

FAQs
Before wiring, confirm the transformer primary voltage options are set for 240 V or 480 V and ensure the 3A wiring connections are used for all terminations. Mount the unit in a level, protected location suitable for a 67P frame, and follow UL Listed installation requirements. Use the indoor-outdoor enclosure where appropriate to meet environmental conditions.
The S20N11P16PSS is a 1.5 kVA, single-phase transformer with a fixed turns ratio: 240/480 V primary to 120/240 V secondary at 60 Hz. This configuration provides consistent control power for typical automation loads and ensures stable output for panel-mounted equipment.
Ideal for industrial control panels, automation cabinets, and machine feeders in manufacturing settings. Its indoor-outdoor capability, NEMA 3R enclosure, and corrosion-resistant Grade 304 stainless steel construction make it suitable for damp workshops, loading docks, and sheltered outdoor locations while delivering reliable control power.
The transformer carries UL Listed certification, confirming compliance with safety standards. It is backed by Eaton's warranty policy, providing one year from installation or eighteen months from shipment, whichever occurs first, offering predictable service life and protection against early failures.
Encapsulation reduces moisture and dust ingress, lowering maintenance needs and extending service life. The rugged enclosure, fixed turns ratio, and simple wiring minimize downtime during commissioning, delivering a faster return on investment by reducing field-service interventions and enabling more reliable operation in automated production lines.
