FAQs
The S20N11P16S6 is a general purpose encapsulated transformer that steps down 240/480 V to 120/240 V at 60 Hz. It provides a reliable 1.5 kVA supply for PLCs, sensors, relays, and control circuits within automation cabinets and machine enclosures. Its rugged design supports consistent operation across varied industrial environments.
Primary voltages are 240 V or 480 V, and secondary voltages are 120 V and 240 V. The transformer operates at a 60 Hz frequency and is rated for 1.5 kVA, making it suitable for typical control and automation loads in manufacturing environments.
Yes, the unit is specified as indoor-outdoor with an enclosure note referring to a Grade 316 stainless steel option. This provides improved corrosion resistance for exposed environments, though the catalog note specifies that enclosure grade does not automatically imply NEMA 4X rating; confirm exact ratings with Eaton for your site requirements.
Warranty terms follow Eaton Selling Policy 25-000: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. This supports maintenance planning and helps constrain lifecycle costs for maintenance teams and procurement managers.
The transformer uses a 67P frame with a 3A wiring connection, designed for straightforward mounting in standard control panels. Plan for appropriate clearances, proper heat dissipation for the 115 °C rise, and secure electrical connections to avoid thermal or mechanical stress in confined spaces.
