FAQs
The N48D28T1221LS50 is a three-phase transformer with a 480 V primary and 208Y/120 V secondary. Ensure your switchgear and distribution panel accept a 112.5 kVA, 480 V input and connect to the 208Y/120 V secondary. Check available footprint (51 in height, 34.5 in width, 31.5 in depth) and confirm UL Listed installation suitability. Consider D-Tap options for voltage stability and verify the 150 °C rise rating aligns with your cooling strategy.
K-Factor nonlinear performance (K13) indicates the transformer is optimized for loads with harmonic currents and non-linear devices. This reduces overheating, maintains voltage stability, and extends insulation life under harmonic demand. For facilities with VFDs, switching power supplies, or other nonlinear sources, the N48D28T1221LS50 maintains efficiency and reliability more effectively than linear-design transformers.
Yes. The 112.5 kVA, three-phase unit with 480 V to 208Y/120 V outputs is well-suited for data centers and manufacturing lines. The K-Factor design handles harmonics from VFDs, while DOE2016 efficiency lowers energy cost. UL Listing adds safety assurance, and its robust frame supports continuous operation in demanding environments.
Key certifications include UL Listed safety and DOE2016 Efficient compliance. These indicate safety conformity and energy performance aligned with modern regulatory expectations. This combination supports safer installations, reduced energy penalties, and smoother procurement approval for regulated facilities and utility programs.
Expect typical transformer maintenance: periodic insulation checks, thermal monitoring, and inspection of connections. The K13 K-Factor design helps tolerate harmonic loading, potentially reducing overheating-related maintenance. With UL safety certification and DOE2016 efficiency, long-term energy savings contribute to a favorable ROI, while the robust ventilated frame supports dependable uptime in harsh environments.
