FAQs
This unit measures 32.65 in by 57.54 in by 36.69 in and weighs about 2,282 lb, requiring adequate floor loading, clearance for maintenance, and proper mounting. Plan access to taps and cables, and consider WS37 weather shielding if installed outdoors. Ensure electrical room ventilation supports its 150°C rise and maintain compliance with NEMA TP-1 standards.
K-Factor nonlinear design optimizes thermal behavior under non-sinusoidal loading, reducing harmonic heating and extending insulation life. This translates to lower maintenance needs, improved uptime, and better overall efficiency for motor drives and process equipment that create harmonic distortion.
Yes. With 225 kVA rating, 480 V primary, 208Y/120 V secondary, and voltage taps for regulation, it supports sensitive IT loads and heavy motors alike. The UL Listing and NEMA TP-1 efficiency, combined with controlled sound (50 dB), make it appropriate for spaces where reliability and acoustic standards matter.
The N48M28T22CUEELS50 is UL Listed and NEMA TP-1 compliant, with a low sound profile suitable for noise-constrained areas. It also features electrostatic shielding and WS37 weather protection for outdoor or rugged environments, aligning with industry electrical and EMI performance requirements.
Copper windings and robust cooling reduce resistive losses and thermal stress, lowering ongoing maintenance needs. The unit’s rated 225 kVA and voltage-tap flexibility support longer service intervals, enabling predictable ROI through improved uptime and energy efficiency in manufacturing and data-center environments.
