Designed as a buck-boost general-purpose encapsulated transformer, the S10N04A05N provides stable voltage to control panels and automation circuits. This translates to smoother motor control and fewer nuisance trips in equipment subject to minor mains fluctuations, boosting overall process stability in production lines and packaging systems. Aluminum coil construction and epoxy encapsulation deliver rugged durability, minimizing corrosion risk and vibration-related wear. The result is lower maintenance costs and longer service life for decentralized power supplies in harsh manufacturing environments and outdoor installations. NEMA 3R enclosure and indoor-outdoor rating keep critical power conversion safe from weather and contaminants, enabling outdoor installations without extra housings, saving space and installation time. With a 5 kVA rating at 60 Hz single-phase, primary options of 120/240 V and secondary 12/24 V meet common automation loads and PLC power rails, while fixed taps (None) simplify wiring and reduce configuration errors. UL Listed certification and a 1-year Eaton warranty provide safety, compliance, and post-purchase support. Dimensions of 9.89 in L, 14.75 in H, and 10.38 in W with a 117 lb weight illustrate a compact yet rugged profile suitable for dense panel layouts and equipment rooms.

FAQs
The S10N04A05N is a 5 kVA, single-phase transformer with 120/240 V primary and 12/24 V secondary. Its dimensions (9.89 in L x 14.75 in H x 10.38 in W) and 117 lb weight require a sturdy mounting surface and, if needed, mechanical handling equipment. With a NEMA 3R enclosure and indoor-outdoor rating, it suits both indoor cabinets and outdoor mounting locations, reducing the need for additional enclosures.
This model is a buck-boost general-purpose encapsulated transformer designed to stabilize voltage in automation circuits facing supply fluctuations. With 120/240 V input and 12/24 V output, it maintains consistent control voltages for PLCs, drives, and sensors, improving uptime and reducing fault conditions caused by voltage drops or spikes in manufacturing lines.
Yes. The transformer features a NEMA 3R enclosure and an Indoor-Outdoor weathershield specification, enabling reliable operation in outdoor environments without additional housing. This protection helps resist dust, moisture, and temperature changes, simplifying installation in yards, outdoor equipment rooms, or weather-exposed panels.
The S10N04A05N is UL Listed, indicating compliance with recognized safety standards. It is designed for 60 Hz, single-phase operation with a fixed 120/240 V primary and 12/24 V secondary. The combination of UL certification and rugged enclosure provides confidence for industrial procurement, safety audits, and maintenance planning in manufacturing facilities.
With aluminum coil construction and epoxy encapsulation, the unit is built for durability in vibration-prone and harsh environments, reducing corrosion and wear. The 1-year warranty from Eaton adds support coverage, while the 5 kVA rating aligns with typical automation loads. Routine inspection of enclosure integrity and electrical connections is advised, but the design minimizes maintenance frequency and costs over the service life.
