Indoor-Outdoor
Encapsulated copper-wound construction provides a rugged, thermally stable core for continuous duty in industrial environments. The epoxy encapsulation eliminates stray moisture pathways and reduces vibration-related wear, which translates to longer intervals between maintenance and fewer on-site service calls. With 1 kVA rating at 60 Hz, this transformer delivers consistent power to control circuits and automation equipment without overloading the circuit. Durable enclosure and mounting versatility support rapid deployments from new panels to retrofit projects. A NEMA 3R rating enables indoor-outdoor installation, while wall-mount capability reduces panel footprint and simplifies service access in cramped electrical rooms. The compact dimensions—6.56 in deep, 13.03 in high, 5.53 in wide—coupled with a 25 lb weight, streamline handling and installation. Voltage compatibility is aligned with common industrial power rails, supporting 240 V or 480 V primary inputs and delivering 120/240 V on the secondary. This makes it ideal for delivering control power from standard plant transformers, supporting a wide range of automation sensors, relays, and motor-control circuits while maintaining efficiency and minimizing heat rise in enclosures. Durability and compliance converge with straightforward maintenance requirements. Copper windings resist corrosion and deliver high conductivity, while 180 °C insulation supports sustained temperature performance. The 60 Hz frequency rating and 1 kVA capacity ensure reliable load handling across machine tooling, conveyor systems, and process-control panels, reducing downtime and replacement costs. UL Listed safety, a one-year warranty, and Eaton support underpin risk management for procurement teams. The combination of robust performance data, documented specifications, and listed certification reduces qualification cycles and accelerates project approvals. When you need a dependable, easy-to-spec transformer for mixed indoor-outdoor environments, this unit delivers consistent results. Together these attributes support installation efficiency, stock-keeping simplification, and energy-conscious operation in busy facilities. Its wall-mount design and standard port spacing also simplify retrofits in legacy equipment rooms. This reduces installation time by hours in large projects.
