The K-Factor nonlinear design reduces harmonic distortion and related heat, which translates to cooler operation and lower cooling energy requirements in high-load environments. This directly improves overall system efficiency and extends transformer life, reducing total cost of ownership for data centers and automated manufacturing lines. In practice, the Eaton N48M28F4521CULS43 supports reliable service in three-phase power distribution with a 45 kVA rating and 480-208Y/120 output, enabling compact yet capable mid-range installations without oversized equipment. The vented XFMR construction enhances airflow, lowering hotspot risk and enabling simpler ventilation planning and cabinet integration in space-constrained sites. With UL Listed certification, the unit aligns with strict safety and installation standards, simplifying code compliance and permitting. The 24 in L, 30.5 in W, 43 in H footprint and 680 lb weight offer a stable, easy-to-mount solution with predictable weight handling and rack/ cabinet compatibility, reducing crane and handling concerns on site. Finally, field compatibility with Eaton’s Transformer Flex Center resources and datasheets supports straightforward configuration, maintenance, and lifecycle management, minimizing downtime and accelerating project timelines.
