FAQs
The N48D28T1521CU is designed for 3-phase 480V primary input with a 208Y/120V secondary. Plan for a sturdy floor mounting or cabinet enclosure, allow clearance for ventilation, and verify D-Tap options match the desired secondary voltage. For best results, coordinate with facility electrical drawings and crane access if needed due to its 430 lb weight.
K-Factor nonlinear design targets higher harmonic content in nonlinear loads, reducing resonant risk and improving overall power quality. This leads to lower heat generation in downstream equipment, fewer nuisance trips, and more stable voltage profiles across sensitive loads such as drives and CNC machinery.
Yes. With a 15 kVA rating, 480V to 208Y/120V outputs, DER-rated efficiency, and a K13 design, it supports critical load centers while maintaining energy efficiency. Its robust UL Listed safety and DOE2016 efficiency alignment make it a strong fit for data centers, automation floors, and industrial plants needing reliable power with controlled harmonic distortion.
The N48D28T1521CU carries UL Listed certification and conforms to DOE2016 Efficient standards. These certifications help meet safety and energy-performance requirements, streamline procurement, and simplify compliance during regulatory audits or facility certifications.
