FAQs
The unit is a three-phase transformer with a 480 V primary and 208Y/120 V secondary. Plan for its footprint (31.5 in D, 51 in H, 34.5 in W) and weight (approximately 1200 lb), requiring appropriate lifting and clearance. Use wiring connection 283B and follow local codes; ensure ventilation to maintain thermal performance.
The N48M28F4921TR features a K-Factor design (K13) that mitigates harmonic currents, improving power quality for sensitive equipment. This reduces overheating risk and equipment stress, supporting more stable PLCs, drives, and automated loads in industrial environments while maintaining efficiency and safety.
Yes, with a 150 kVA rating and 480 V to 208Y/120 V outputs, it is well suited for manufacturing lines and data-center-like environments that require reliable, conditioned three-phase power. The DOE2016 Efficient and UL Listed features provide energy savings and safety assurance, supporting compliance and uptime across critical loads.
This transformer carries UL Listed certification and DOE2016 Efficient compliance. UL Listing supports safe installation and maintenance across facilities, while DOE2016 Efficient status signals reduced energy losses. These certifications help streamline procurement, reduce risk, and align with corporate energy programs.
Expect lower operating costs due to DOE2016 efficiency and reduced cooling load from the ventilated design. Maintenance focuses on periodic cleaning of cooling paths, verifying vent integrity, and inspecting connections (283B) and mounting hardware. The result is improved uptime, longer service life, and a favorable total cost of ownership for power-management needs.
