The encapsulated, general-purpose design provides ready-to-use control power in tight spaces, with windings protected from dust, moisture, and contaminants to reduce field faults and maintenance costs. This 10 kVA single-phase transformer accepts 240/480 V primaries and delivers 120/240 V secondaries, enabling direct integration with common plant power rails and minimizing inventory complexity. The NEMA 3R enclosure supports indoor-outdoor deployment, while the low 47 dB sound level ensures quieter operation on busy factory floors and in nearby work areas. Aluminum coil construction improves corrosion resistance and thermal performance, contributing to longer service life in harsh environments. UL Listed certification confirms regulatory compliance, and the 80 °C rise rating enables reliable operation in elevated ambient temps. Overall, installation is simplified by the compact footprint and straightforward wiring (3A), reducing total cost of ownership over the product life cycle.
