FAQs
The N48M28F4921SR uses the standard 283B wiring connection and a robust frame suitable for floor installation in industrial switchgear environments. With a 31.5 in depth, 34.5 in width, and 51 in height, it requires adequate space for mounting, ventilation, and safe lifting. Ensure the site has proper clearance for service access and cooling airflow, and plan crane support for initial placement given the 1200 lb weight.
K13 K-Factor indicates enhanced efficiency under nonlinear loading conditions, typical of motors, drives, and power electronics. This reduces copper and iron losses during harmonic-rich operation, lowers transformer temperature rise, and improves overall reliability. In practice, users see lower energy costs and improved voltage regulation in facilities with variable demand and harmonic generation.
Yes. The N48M28F4921SR’s K13 energy efficiency and DOE2016 design optimize performance under nonlinear loads common in data centers and manufacturing plants. It provides 150 kVA capacity, a 480 V primary, and 208Y/120 V secondary, delivering stable control power and critical-load support while maintaining thermal and efficiency targets in demanding environments.
The transformer is UL Listed and meets DOE2016 Efficient standards, with K13 energy efficiency features. These certifications ensure compliance with safety and energy regulations, facilitate procurement for regulated facilities, and support code-aligned installation. For projects requiring formal safety approvals and energy-performance evidence, these credentials streamline commissioning and audits.
Deploying the N48M28F4921SR can reduce lifecycle costs through lower no-load and load losses due to DOE2016 efficiency and K13 performance. Though initial installation requires careful planning for its 1200 lb weight and space needs, long-term savings come from cooler operation, extended transformer life, and reduced energy consumption in harmonic-rich environments, improving total cost of ownership over the asset’s life.
