Eaton N48M28T45 Ventilated Transformer - UL Listed
Part Number: N48M28T45
Quick Summary
Eaton K-Factor nonlinear ventilated transformer is designed to power critical three-phase loads with reliable thermal management in demanding industrial environments. This model addresses common challenges around heat buildup, voltage stability, and space-constrained panels by blending robust cooling with precise taps and solid construction. UL Listed certification supports safety and regulatory compliance in manufacturing, data centers, and automation facilities. With PV 480V primary and SV 208Y/120V secondary, plus two +2.5% and four -2.5% taps, it tolerates modest voltage variations without sacrificing performance. The design also leverages aluminum windings and an electrostatic shield to improve efficiency and fault isolation, while the WS39 weather shield expands installation options in harsher environments. Businesses gain uptime, simplified maintenance, and predictable power for critical loads.
