A general-purpose encapsulated transformer is a compact, single-phase device that delivers reliable voltage conversion for control panels and industrial equipment. It leverages an EP design with aluminum coil material to maximize durability while minimizing weight and thermal losses. The 5 kVA rating supports a range of automation loads, enabling designers to power PLCs, drives, and control circuits from common 208/416 V supplies to 110/220 V loads. The NEMA 3R enclosure and indoor-outdoor weathershield provide versatile installation in both protected and harsher environments, reducing site downtime and weather-related failures. Tap settings of 2 at -5% and 4 at -2.5% FCBN offer voltage regulation to compensate for line drop and loading variations, improving system stability. The transformer’s wiring scheme, 23A16, simplifies panel integration and reduces field-adjustment needs, while its 50/60 Hz catalog notes ensure compatibility with global electrical codes.

FAQs
For installation, plan for the 9.89 in depth, 10.38 in width, and 16 in height footprint with a weight of 130 lb. Mount the unit on a sturdy base or panel rack, allowing clear access for wiring 23A16 and tap adjustments. Utilize the NEMA 3R enclosure for indoor-outdoor use and ensure 50/60 Hz operation per catalog notes. Leave space for ventilation and verify UL Listed compliance during final wiring.
The transformer supports 208 V and 416 V primary voltages and 110/220 V secondary voltages. Tap settings are 2 at -5% FCBN and 4 at -2.5% FCBN, allowing regulation to compensate for line drops or loading variations. Use the taps during commissioning to achieve desired secondary voltage under load, maintaining system stability and meeting device voltage requirements without oversizing components.
Yes, the S18L14S05X is designed for indoor-outdoor use, featuring a weather-resistant indoor-outdoor Weathershield and a NEMA 3R enclosure. This combination provides protection against dust, moisture, and certain corrosives, enabling reliable operation in variable environments. When installing, ensure seal integrity around wiring connections and maintain clearances per installation guidelines to optimize heat dissipation.
The product is UL Listed, supporting compliance with common safety standards in North America. Catalog notes indicate 50/60 Hz operation, aligning with global utility grids. While SIL or CE certifications are not listed in the data, the UL Listing and NEMA 3R enclosure confer essential safety and environmental suitability for industrial applications. Always verify local code requirements for your region.
With a 5 kVA rating and a rugged encapsulated design, the transformer minimizes downtime and maintenance costs typical of less robust units. Aluminum windings and a durable EP enclosure reduce corrosion and heat-related failures, extending service life. The included warranty and standard field-serviceability support predictable lifecycle costs, while the compact footprint reduces installation labor and cabinet real estate, enhancing overall return on investment for panel builders and automation integrators.
