FAQs
The N48D28T4521CU is a heavy-duty, 430 lb transformer with three-phase 480 V primary and 480/208Y/120 V secondary. It supports standard industrial mounting approaches and D-Tap configurations for flexible tap connections. When planning installation, ensure adequate clearance for venting, access for maintenance, and compatible enclosure ratings; verify lid and panel cutouts align with the 21.13 in length, 36.88 in height, and 24.88 in width dimensions.
K-Factor nonlinear design targets high-harmonic loads, reducing peak currents and circulating harmonics that would otherwise elevate winding temperature. This improves thermal margin and expands continuous duty capability in non-linear load scenarios common in drives and power electronics. With DOE2016 efficiency in mind, the transformer maintains performance while conserving energy, which is critical for facility cooling budgets and equipment longevity.
Yes. The N48D28T4521CU is well-suited for data centers, machine rooms, and automation panels that require reliable 3-phase power with clean secondary voltages. Its 480 V primary and 480/208Y/120 V secondary configuration aligns with common data hall and control cabinet standards, while UL Listed certification supports procurement in regulated environments and helps meet project commissioning timelines.
This transformer carries UL Listed safety certification and DOE2016 Efficient compliance. UL Listed indicates adherence to recognized safety standards for electrical equipment, reducing risk in installation and operation. DOE2016 Efficient designation signals energy-performance compliance that helps lower operating costs and supports sustainability goals in large facilities and data centers.
