FAQs
Plan for a three-phase, 480 V to 208Y/120 V connection with a compatible 912B frame enclosure. Ensure adequate ventilation and clearance for the 115°C rise rating, and account for the 356 lb weight with proper lifting equipment. Use the taps to fine-tune voltage during commissioning and verify UL-listed protection clearances per local codes.
Key specs include 15 kVA rating, 60 Hz frequency, primary 480 V, secondary 208Y/120 V, copper windings, and K-Factor nonlinear design. Also note the +2.5% / -2.5% tap capability, 115°C rise, and 40 dB low-noise operation, which together support stable voltage under harmonic-rich conditions.
Yes. The K-Factor nonlinear ventilated design handles harmonic loading common in data centers and manufacturing with variable-speed drives. The 15 kVA rating, tight voltage regulation via taps, and UL/NEMA TP-1 compliance make it a reliable choice for critical loads and compliant environments.
The N48M28F15CUEELS40 is UL Listed and NEMA TP-1 compliant, ensuring safety and efficiency for regulated installations. Its low-noise profile and electrostatic shielding further support compliance with noise and EMI considerations in modern facilities.
With copper windings, efficient operation, and a robust 115°C rise rating, the transformer reduces cooling load and energy losses, translating to lower operating costs. The UL/NEMA TP-1 certifications simplify ongoing compliance audits, while the 25-000 warranty window supports predictable maintenance planning and long-term reliability.
