FAQs
Installation requires a 916A frame base, with mounting dimensions of 23.42 in L, 28.22 in W, and 48.56 in H. The WS19 weather shield provides environmental protection for outdoor or harsh environments, while the aluminum coil and ventilated design aid heat dissipation. Plan for three-phase 480 V input and 208Y/120 V output, plus the secondary tap options to fine-tune voltage under load.
The unit features a 480 V primary and a 208Y/120 V secondary. Tap settings are 2 taps at +2.5% and 4 taps at -2.5% to accommodate feed variations and load changes, helping maintain output voltage within tolerance across operating conditions.
Yes, it is UL Listed and NEMA TP-1 compliant. UL Listing confirms component safety and reliability for electrical installations, while NEMA TP-1 compliance ensures transformer efficiency and performance are suitable for commercial and industrial power distribution, reducing regulatory risk and facilitating approvals.
Yes. The N48M28F75EES2LS47 uses a K-Factor nonlinear design to better handle harmonic currents from non-linear loads, improving power quality, reducing converter and drive stress, and supporting compliance with harmonic limits in industrial networks.
ROI comes from improved uptime, reduced harmonic-related losses, and energy-management gains from stable voltage regulation. Maintenance is typically straightforward: periodic inspections, insulation checks, and routine thermal and oil-free assessment are simplified by the robust aluminum-wound design, compact footprint, and Eaton warranty terms (one year from installation or eighteen months from shipment, whichever comes first).
