Encapsulated transformer
Encapsulated enclosure protects windings from moisture, dust, and incidental exposure, while providing robust mechanical support in panel environments. This design reduces the risk of insulation degradation and unplanned outages, delivering higher reliability and lower maintenance costs over the life of the equipment. It is ideal for control cabinets in manufacturing lines, robotics cells, and automated feeders where ambient conditions can vary and space is at a premium. With a 3 kVA, 1-phase, 480-120/240 configuration, the S48N11E03CU delivers versatile secondary voltages for PLCs, relays, sensors, and I/O modules. This rating accommodates typical automation loads without oversizing, enabling a leaner panel design and reduced heat generation. In new builds or panel upgrades, this transformer simplifies procurement by matching common automation power requirements while retaining headroom for startup surges. Copper windings provide lower resistance and tighter voltage regulation under fluctuating loads, improving drive performance for motors and actuators and enhancing overall panel stability. The improved efficiency reduces energy waste and lowers cooling requirements, which translates into ongoing operating cost savings. For facilities with continuous uptime targets, this translates into measurable reliability benefits and predictable performance. Installation is streamlined by Eaton’s established cataloging and datasheets; S48N11E03CU is listed in commercial distribution references with an accompanying specification sheet. Field service becomes faster when technicians have access to trusted Eaton references during commissioning and maintenance. The encapsulated transformer also supports standard panel mounting practices and compatibility with common enclosure frames, reducing integration risk and avoiding custom solutions. Certification status is region-specific; confirm CE marking, UL recognition, and CSA status with Eaton prior to deployment. If your project demands SIL ratings or IP protection data, consult Eaton to verify suitability and any upgrade options. For procurement and lifecycle value, consider the long-term reliability, spare parts availability, and the strong warranty support that accompanies Eaton power components.

FAQs
To install the S48N11E03CU, mount the encapsulated transformer inside the control panel using standard chassis hardware to a rigid frame, then connect the 480 V input terminals to the primary and the 120/240 V secondary to the control circuits. Follow lockout-tagout procedures and secure wiring with appropriate clamps. Refer to Eaton wiring diagrams in the datasheet during commissioning.
Key specifications include a 3 kVA rating, single-phase operation, primary voltage of 480 V, secondary voltage of 120/240 V, copper windings, and a 115°C temperature rise. These specs support PLCs, relays, sensors, and other automation loads with stable voltage under varying conditions. Consult the S48N11E03CU datasheet for exact regulation curves and tolerances.
Yes, the encapsulated design provides moisture and dust resistance, improving reliability in factory floors. For harsh environments, verify enclosure IP rating and regional approvals with Eaton, and ensure proper panel sealing and ventilation to maintain cooling and efficiency during continuous operation.
Certification status is region-specific; confirm CE marking, UL recognition, and CSA status with Eaton prior to deployment. If your project requires SIL ratings or IP protection data, request confirmation from Eaton and reference the specification sheet to ensure regulatory alignment across locations.
The encapsulated design minimizes maintenance due to moisture protection and robust windings, reducing downtime. The 3 kVA rating supports scalable automation loads, decreasing the need for multiple smaller transformers. Access to Eaton datasheets accelerates procurement, commissioning, and long-term spare parts planning, delivering predictable total cost of ownership for panel power solutions.
