Eaton Specification Sheet - N48M28F12CUEELS47
K-Factor nonlinear ventilated design helps mitigate harmonic distortion and hotspot formation. The business impact is reduced thermal stress on windings and downstream equipment, which translates into longer service life and lower maintenance. In practice, this is ideal for motor drives, inverters, and other nonlinear loads common in modern plants. Voltage regulation is supported by taps at +2.5% and -2.5% to accommodate supply variability on a 480 V primary and 208Y/120 V secondary. The business impact is tighter voltage control and fewer nuisance trips or faults in sensitive equipment. This is beneficial for CNCs, PLCs, and automation panels in manufacturing lines. The 112.5 kVA three-phase rating provides robust headroom for growth, reducing the need for utility upgrades and lowering lifecycle costs. Copper windings offer higher efficiency and better thermal performance, delivering energy savings and improved reliability in continuous operations. The 47 dB sound level and electrostatic shielding reduce EMI, enabling closer equipment layouts and quieter plant environments. Weathershield WS19 expands outdoor viability, while a 115°C rise rating ensures the transformer withstands peak loading. All of these features come with UL Listed and NEMA TP-1 compliance, backed by Eaton’s 1-year warranty, delivering confidence in procurement and installation.

FAQs
Ensure correct mounting and clearance for a heavy 112.5 kVA transformer in a suitable enclosure or pad. Verify 480 V primary supply, 208Y/120 V secondary distribution, and three-phase equipment compatibility. Consider WS19 weather shielding for outdoor or semi-outdoor placements and provide adequate ventilation to maintain the stated 115°C rise limit.
Key specs include 112.5 kVA rating, 480 V primary, 208Y/120 V secondary, 60 Hz, copper windings, and taps at 2 at +2.5% and 4 at -2.5%. Taps enable fine voltage regulation to keep downstream equipment within tolerance, reducing nuisance trips and improving control stability in sensitive loads like PLCs and drives.
Yes, its nonlinear K-Factor design mitigates harmonic stress common with motor drives and power electronics, while the 47 dB low-noise profile suits installation near personnel. For data centers, stable voltages and EMI reduction via shielding support reliable IT and control systems.
The transformer is UL Listed and NEMA TP-1 compliant, signifying safety, reliability, and efficiency per industry standards. These certifications simplify procurement for regulated facilities, support warranty eligibility, and help meet corporate and project-specific compliance requirements.
Expect routine inspections of connection integrity, oil-free copper windings, and verification of tap settings during commissioning. The 1-year warranty and robust build reduce risk, while the unit’s efficiency and voltage regulation capabilities lower operating costs and downtime, delivering a favorable return on investment over its service life.
