2 kVA, 60 Hz single-phase operation provides isolated power for multiple control loads, reducing cross-talk and protecting sensitive electronics. This translates to lower downtime and improved equipment reliability in panel-mounted applications. Encapsulated EP construction with an aluminum coil offers enhanced moisture resistance and vibration protection, enabling installation in challenging environments such as damp workshops or outdoor enclosures. The NEMA 3R enclosure supports indoor-outdoor mounting, reducing the need for additional protective housings and expediting installation in outdoor control cabinets. The -5% FCBN tap option supports voltage regulation to compensate for supply variations, helping maintain downstream equipment performance and reducing nuisance tripping in sensitive control circuits. With UL Listed safety certification and compact dimensions, this transformer integrates easily into standard factory layouts, improving procurement efficiency and ensuring regulatory compliance. The indoor-outdoor readiness and rugged build also contribute to lifecycle cost reductions by minimizing maintenance needs and unexpected replacements in high-demand automation lines.
