Eaton N48M28F12LS45 Transformer - 112.5 kVA UL Listed
Part Number: N48M28F12LS45
Quick Summary
The Eaton K-Factor nonlinear ventilated transformer delivers reliable three-phase power conditioning for demanding industrial environments. Engineers often contend with noise, heat, and downtime in transformer rooms; this unit mitigates those challenges with a low-sound, ventilated design. UL Listed safety certification anchors compliance, while the 115 °C rise rating, aluminum windings, and electrostatic shielding support robust operation in hot, harsh facilities. With 480 V primary and 208Y/120 V secondary, two taps at +2.5% and four taps at -2.5% provide voltage regulation for diverse feeders, enabling fast installation and long-term lifecycle value for production floors and data centers.

FAQs
N48M28F12LS45 supports a 480 V primary and a 208Y/120 V secondary. It provides voltage regulation via taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling precise secondary voltage under fluctuating feeds and long feeders. Install per UL and local electrical codes.
The N48M28F12LS45 uses a K-13 design to tolerate nonlinear loading, such as nonlinear harmonics from variable-speed drives, with controlled temperature rise. It combines aluminum windings, an electrostatic shield, and a ventilated core to manage losses, EMI, and thermal stress in demanding installations.
Yes. The transformer is designed for low noise, delivering approximately 45 dB, and uses a ventilated construction with insulation rated for a 115 °C rise. The WS34 weather shield adds outdoor durability, supporting reliable operation near equipment rooms and unconditioned spaces.
The Eaton unit carries a one-year warranty from installation or 18 months from shipment. Its 112.5 kVA rating reduces the need for multiple transformers, while UL safety certification and rugged aluminum windings lower maintenance costs and downtime, delivering predictable lifecycle value.
Ideal for industrial facilities, automation cabinets, data centers, and manufacturing lines requiring stable distribution voltage. Its 480 V to 208Y/120 V output, rugged construction, and taps for voltage adjustment make it well suited for power distribution rooms, control panels, and harsh environments.
