Eaton N48M47F49CUEELS45 K-Factor Transformer - UL Listed
Part Number: N48M47F49CUEELS45
Quick Summary
Eaton K-Factor nonlinear ventilated transformer enables efficient three-phase power conditioning for data centers and industrial facilities. It addresses voltage stability and harmonic distortion that challenge aging electrical systems with mixed loads. The unit is UL Listed, with a NEMA 2 enclosure and a low sound design that ease installation in crowded or noise-sensitive environments. Copper windings and configurable taps support precise voltage shaping at 480 V primary and 480Y/277 V secondary, under 60 Hz, delivering predictable performance and reduced heat losses. The robust mechanical design, 150 kVA rating, and 115 °C rise offer reliable service in demanding environments, while warranty terms—one year from installation or eighteen months from shipment—support total cost of ownership. This combination aligns with power management and infrastructure investment strategies.
