Feature → Business Impact → Application: General-purpose encapsulated transformer design using copper windings (EP) delivers high reliability and low core losses, translating to improved efficiency and reduced cooling requirements in continuous operation. This supports critical panel boards and machine controls where steady voltage transformation is essential for uptime and product quality. Feature → NEMA 3R enclosure with indoor-outdoor protection enhances ruggedness and weather resistance, reducing enclosure-related downtime in outdoor or harsh indoor environments, a boon for outdoor substations and exterior equipment closets. Feature → 5 kVA, 60 Hz, single-phase configuration provides predictable load handling with compact footprint, enabling easier integration into control panels and small switchgear enclosures while meeting common plant distribution needs. Feature → Copper coil winding and robust encapsulation improve temperature stability and dielectric strength, supporting longer service life and safer operation in high-humidity facilities. Feature → Tap changer “2 at -5% FCBN” and 2D wiring connection simplify on-site voltage tuning and wiring layouts, cutting installation time and enabling quick adaptation to minor voltage swings in manufacturing lines. Feature → UL Listed certification and NEMA 3R-rated enclosure align with industry codes and safety standards, facilitating faster procurement, compliance audits, and safer maintenance routines. Weighing 116 lb with precise dimensions, the unit fits standard mounting footprints while offering solid mechanical support for panel-mounted installations. Warranty coverage of one year from installation (or 18 months from shipment) provides a predictable, risk-managed lifecycle for procurement teams and maintenance planners.
