Indoor-Outdoor
The encapsulated design protects windings from dust, moisture, and incidental contact, reducing maintenance costs and extending service life in harsh environments. This translates into fewer unscheduled outages in control panels and in distributed power systems, enabling reliable operation of automation equipment. For engineers, the compact footprint fits tight spaces within equipment racks, while still delivering 15 kVA of capacity, ensuring you can consolidate loads without oversizing infrastructure. The single-phase configuration with primary voltages of 190/200/208/220/380/400/416/440 V and a secondary of 110/220 V provides flexible sourcing across regional grids. Industry teams benefit from reduced inventory complexity and faster replacement cycles on compatible drives and sensors, especially in mixed-voltage facilities. The UL Listed and CE Marked compliance, along with a NEMA 3R indoor-outdoor enclosure, offer strong regulatory alignment for manufacturing floors and outdoor installations. This reduces risk during audits and supports safer commissioning of power-distribution architectures. Aluminum windings and a rugged frame (182) plus a 23.31 in height by 16.35 in width profile enable easy mounting on standard bases or within cabinet spaces. With a 14.12 in depth and a 369 lb weight, installers gain a stable, vibration-resistant transformer for long-term reliability, while maintaining accessibility for wiring connections (538A) and inspection.

FAQs
The transformer uses a NEMA 3R enclosure designed for indoor-outdoor use, with a 182 frame and a footprint that accommodates mounting on standard bases or within compatible enclosures. Ensure solid footing, adequate clearance around wiring, and, when possible, vibration isolation to maximize long-term reliability.
Primary voltages span 190, 200, 208, 220, 380, 400, 416, and 440 V, while the secondary provides 110/220 V. This single-phase unit operates at 60 Hz, offering flexible voltage conversion to meet regional grid needs and equipment requirements in control panels and distributed power systems.
Yes. The S40N14S15CE is UL Listed and CE Marked, indicating compliance with safety and performance standards. The enclosure supports indoor-outdoor operation, and the unit uses aluminum windings with a 115 °C rise rating, ensuring robust performance in demanding environments.
Prioritize a solid mounting surface, maintain adequate clearance for ventilation and wiring, and use the 538A wiring connection with appropriate terminations. The aluminum windings, 23.31 in height, 16.35 in width, and 14.12 in depth contribute to a stable, vibration-resistant footprint ideal for control rooms and outdoor installations.
Expect long service life from the encapsulated design and reduced maintenance due to sealed windings. The rugged construction minimizes downtime in critical automation circuits, while the UL CE certifications simplify audits. A one-year warranty from installation or eighteen months from shipment provides lifecycle protection, supporting lower total cost of ownership in plant-wide power distribution.
