Feature → Business Impact → Application: The 2 kVA single-phase transformer delivers essential isolation and voltage transformation for control circuitry, improving system safety and reducing stray voltage concerns in harsh environments. This translates to measurable efficiency gains and lower maintenance costs when powering PLCs and relays in confined spaces. The aluminum windings and EP encapsulation minimize thermal losses and moisture ingress, supporting reliable operation in years-long production lines and outdoor installations. Application-wise, the S20N11P02PSS fits 68P frames for easy panel mounting and a 6.32 in depth, 13.78 in height, and 6 in width footprint that suits compact enclosure designs. Compatibility with indoor-outdoor Weathershield enclosures and UL-listed compliance helps streamline procurement and commissioning. Common objections about outdoor reliability are addressed by NEMA 3R protection, Grade 304 stainless steel enclosure notes, and a proven 60 Hz performance.

FAQs
Installation should begin with confirming enclosure clearance for a 68P frame, wiring with the 3A connection, and securing the transformer to the panel backplate. Mounting should respect the 6.32 in depth and the overall 6 in width, ensuring proper ventilation. Use appropriate lugs and follow UL-listed installation practices for indoor-outdoor use, including strain relief and short-circuit protection.
This unit is a single-phase, 2 kVA transformer with 240/480 V primary and 120/240 V secondary, operating at 60 Hz. It uses aluminum windings and supports a 115 °C rise, with a 3A wiring connection. These specs map to control circuits and PLC distributions requiring isolation and voltage conversion while maintaining compatibility with standard industrial power rails.
Yes. The transformer is designed for indoor-outdoor service with a NEMA 3R enclosure configuration and Weathershield suitability. Grade 304 stainless steel enclosure notes further enhance corrosion resistance in challenging environments, making it appropriate for outdoor shelter installations or exposed facilities where control power reliability is critical.
The S20N11P02PSS is UL Listed, which supports safety compliance in North American industrial environments. The enclosure and materials are selected for rugged duty, with the NEMA 3R rating providing protection against weather elements. The combination of UL certification and robust enclosure design helps streamline regulatory acceptance and maintenance planning.
The transformer carries Eaton’s warranty policy as specified (one year from installation or 18 months from shipment, whichever occurs first). This reduces risk during initial commissioning and supports longer equipment life in automation builds. Its durable enclosure, corrosion-resistant components, and UL-listed safety profile contribute to lower downtime and predictable long-term maintenance costs.
