FAQs
Yes. The N48M47B45EE is a 45 kVA, three-phase transformer rated for 480 V input and 480Y/277 V output, with taps at +2.5% and -2.5% to improve voltage regulation under varying loads. It is designed for seamless integration into standard 480 V distribution schemes, and its aluminum windings and ventilated cooling support reliable operation in typical switchgear enclosures.
Key specs include 45 kVA rating, 60 Hz frequency, 480 V primary, 480Y/277 V secondary, and two +2.5% / four -2.5% taps. The taps allow minor voltage adjustments to compensate for line drop or heavy loading, helping maintain downstream voltage within tolerance and reducing nuisance tripping on sensitive equipment.
Yes. The K-Factor nonlinear design with ventilated cooling is well-suited for harmonic-rich environments like data centers and manufacturing lines. With UL Listing and NEMA TP-1 compliance, it supports stringent reliability and efficiency requirements while providing robust phase-shifted voltage to sensitive loads.
The unit is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficiency considerations. This ensures it meets established safety, performance, and energy efficiency criteria, simplifying procurement, audits, and regulatory alignment for commercial and industrial installations.
The ventilated, K-Factor design reduces overheating risk under nonlinear loads, which minimizes cooling energy and maintenance intervals. With reliable aluminum windings, electrostatic shielding, and certified standards, your operation benefits from lower downtime, predictable performance, and a favorable return on investment in mid-to-large power distribution upgrades.
