Copper windings and the EP encapsulated design reduce stray losses and heat, boosting efficiency and accelerating heat dissipation in confined panel spaces. This translates to lower operating temperatures, extended component life, and fewer mid-life replacements in critical control circuits. In practice, technicians see improved stability in PLC power rails and sensor circuits during startup surges in compact enclosures. With a rugged NEMA 4X enclosure rated for indoor-outdoor service, the S48D11S15CUS64X resists corrosion in damp environments and dusty plants, lowering maintenance cycles and downtime. Rated at 15 kVA, it supports typical panel power needs without oversizing and converts 480 V to 120/240 V for controls and actuators, aligning with standard plant electrical architectures. Voltage taps provide ±2.5% regulation, reducing nuisance tripping and improving control stability across variable loads. The 60 Hz single-phase design further simplifies procurement and spare parts compatibility, while its indoor-outdoor suitability and 115 °C rise rating offer resilience in tough sites. Eaton’s one-year warranty (or 18 months from shipment, per policy) enhances total cost of ownership, making this transformer a dependable choice for long-term operation in automation and power distribution applications.

FAQs
Install the transformer in a compliant enclosure with proper mounting hardware, ensuring adequate clearance for cooling. Connect the 480 V primary to the primary lugs and wire the 120/240 V secondary to the control panel circuits. Use the specified taps (+2.5% and -2.5%) to fine-tune voltage under variable loads. Verify NEMA 4X enclosure integrity for indoor-outdoor environments and confirm mounting coordinates per Eaton installation guidelines.
The S48D11S15CUS64X is a 15 kVA, single-phase transformer rated for 60 Hz operation. Primary voltage is 480 V, secondary voltage is 120/240 V. It uses copper windings and offers voltage taps at +2.5% and -2.5% for regulation. Temperature rise is 115 °C, and the enclosure is rated for indoor-outdoor use with NEMA 4X protection.
Yes. The unit is designed with a NEMA 4X enclosure and is specified for indoor-outdoor use, supported by 316 stainless steel enclosure notes in the catalog. This combination provides corrosion resistance and protection against dust, moisture, and incidental exposure, making it suitable for outdoor or harsh indoor environments when properly installed.
Catalog notes indicate Certification: Contact Manufacturer, with NEMA 4X enclosure highlighted. For formal certifications (such as SIL, CE, IP), consult Eaton's documentation or contact their technical support to confirm current status and any region-specific approvals. In practice, the robust enclosure and industrial ratings ensure alignment with common electrical codes when installed to spec.
Eaton provides a standard one-year warranty from installation or eighteen months from shipment, whichever occurs first. Routine maintenance involves visual inspection of enclosure integrity, torque checks on connections, and temperature monitoring during operation. Copper windings and a robust enclosure contribute to long service life and reduced unexpected downtime in automation and power-distribution applications.
