FAQs
Yes. The N48M28F7521CUOS is configured for 480 V primary and 208Y/120 V secondary, making it suitable for common North American power-distribution architectures. When installing, ensure adequate ventilation, access for service, and compliance with UL Listed safety requirements. Its 430 lb weight and 36.88 in height imply solid mounting on reinforced bases or within switchgear frames designed for medium- to large-kVA transformers.
The K-Factor nonlinear design minimizes additional heating when non-sinusoidal loads are present, helping to keep core and winding temperatures within safe limits. This improves reliability and reduces cooling energy consumption over time. In practice, you gain steadier voltage regulation and expanded tolerance for harmonic currents, which is valuable when driving variable-speed drives, PLCs, and other digital loads in busy manufacturing environments.
Industries with significant harmonic activity and critical uptime, such as data centers, machine shops, and process automation facilities, benefit most from this 75 kVA copper-windings transformer. The combination of high reliability, compact footprint, and robust cooling supports continuous operation under peak loads while preserving power quality for sensitive controls and motor drives.
UL Listed certification indicates compliance with recognized safety standards for electrical equipment, reducing procurement risk and aiding regulatory approvals. This transformer provides a controlled high-power solution with copper windings and a K-Factor design, aligning with industry best practices for electrical safety, arc flash mitigation, and protective relays. For manufacturers, this supports supplier qualification and customer audits.
Expect measurable ROI through reduced energy waste from copper windings and better thermal management, which lowers cooling and maintenance costs over the life of the asset. Routine checks focus on winding insulation, airflow, and UL-listed safety clearances. With a 75 kVA rating, this transformer typically delivers reliable service for many years, minimizing unscheduled downtime and replacement expenses.
