Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated EP design in a rugged NEMA 3R enclosure offers moisture resistance and durability for indoor-outdoor service, which translates to less maintenance and longer service life in demanding environments. Aluminum coil construction reduces weight and simplifies handling, enabling faster installation and lower shipping costs on site. The 50/60 Hz, single-phase configuration provides broad compatibility with existing control circuits and panel boards, delivering dependable power to sensors, PLCs, and relays without reconfiguration. With a 0.075 kVA rating and dual voltage options (240/480 V primary, 120/240 V secondary), the S20N11S85X supports versatile power conversion while minimizing component fatigue and heat in small loads. The compact dimensions (roughly 4 in x 4.11 in x 8.91 in) and 8 lb weight make it ideal for crowded control panels, reducing space penalties and accelerating installation. UL Listed certification and a one-year warranty (or 18 months from shipment, per Eaton policy) provide risk reduction and post-sale support for long-term uptime. This transformer is well-suited for control panels, industrial automation cabinets, and equipment enclosures where rugged reliability and compact form factor are critical.
