Eaton S20N08A51N General purpose encapsulated transformer - UL Listed

Encapsulated EP construction with buck-boost capability protects windings from dust, moisture, and vibration, boosting reliability and equipment life. The rugged encapsulation keeps electrical parts shielded in busy industrial environments, reducing nuisance trips and unplanned downtime. For panel builders, this means fewer enclosure penetrations, simpler wiring schemes, and longer intervals between maintenance cycles, especially in conveyors, presses, and automated assembly lines. The combination of protection and voltage adjustment supports stable operation even when line voltage varies, delivering consistent performance across shifts and seasons. Dual primary voltages of 240 and 480 V along with a 24/48 V secondary enable seamless integration with common plant power systems. That flexibility reduces the need for rewiring, inventory swaps, or additional transformers when upstream supply changes, speeding installation and commissioning. End users gain tighter voltage regulation for control circuits, PLC power supplies, relays, and instrumentation without sacrificing reliability. This makes the S20N08A51N an attractive option for machine builders seeking plug-and-play compatibility across mixed electrical distributions. With a 0.5 kVA rating at 60 Hz, single‑phase, the transformer is sized for low‑power control circuits, sensors, and small drives while remaining robust enough for continuous duty. The compact footprint minimizes cabinet depth and improves airflow, letting OEMs pack more functionality into compact panels. Engineers appreciate predictable voltage delivery under load, reduced heat, and easier thermal management in crowded equipment enclosures. NEMA 3R enclosure and Weathershield designation enable true indoor‑outdoor service, including damp or dusty environments. This weather resistance eliminates the need for extra rugged housings and accelerates field deployments at outdoor equipment bays or production floors. For integrators, the outdoor suitability reduces lead times and aligns with stricter environmental codes when projects cross facility boundaries. Aluminum coil, 57 frame, and a 17 lb weight simplify handling and installation in restricted spaces. Exact dimensions—about 4.9 in wide, 4.9 in deep, and 8.75 in tall—fit typical control panels with limited footprint. The 3D wiring connection and a 115 °C rise margin provide straightforward terminations and reliable operation even in high-ambient conditions, while UL Listed certification supports compliance with electrical codes.
