Eaton Specification Sheet - X48M28F49CUEENONLS52
Tap-enabled voltage regulation provides precise voltage compensation with 2 taps at +2.5% and 4 taps at -2.5%, reducing downstream voltage stress and extending equipment life in demanding manufacturing environments. Copper windings deliver lower resistance and improved thermal performance, boosting efficiency and reducing cooling energy costs in hot plants. The 115°C rise rating supports reliable operation in elevated ambient conditions, minimizing derating and maintenance needs in data centers or automated facilities. An EE core design reduces core losses and improves overall efficiency, translating to measurable energy savings over time. Compatibility with standard low-voltage distribution panels and Eaton’s support network simplifies installation, reduces total project time, and enhances ongoing maintenance. Addressing common objections, this transformer also offers robust durability and easy integration with PV systems, manufacturing lines, and commercial buildings to protect capital investments.

FAQs
Plan for proper enclosure, adequate clearance for cooling, and compliant grounding. Ensure the 480 V supply and 208Y/120 V secondary wiring are correctly terminated and protected. Verify tap settings (+2.5% and -2.5%) are chosen to maintain stable voltage under expected load variations and integrate with existing power management and distribution panels.
Primary voltage is 480 V, secondary voltage is 208Y/120 V, and the volt-ampere rating is 150 kVA. The unit uses copper windings and an EE core, with taps available to adjust voltage by +2.5% or -2.5% to match loading conditions.
Yes. It is designed to mitigate harmonics in 480 V distribution networks, making it well-suited for PV integration, manufacturing floors, and other industrial automation environments. The 150 kVA rating supports medium-scale power needs, while copper windings and robust construction support reliability in demanding facilities.
Current certifications are listed as 'Contact Manufacturer' for this model. To verify CE, SIL, IP, or UL certifications, contact Eaton directly or consult the official datasheets. Confirm compliance with local electrical codes and project requirements before procurement or installation.
Harmonic mitigation lowers losses and reduces stress on downstream equipment, contributing to improved efficiency and longer asset life. ROI depends on harmonic levels, energy costs, and application uptime. Maintenance is typically routine, focusing on thermal performance and connection integrity; Eaton’s support network can assist with commissioning and ongoing service.
