FAQs
Plan for a three-phase 60 Hz environment with a 480 V primary and 208Y/120 V secondary. The unit weighs about 1000 lb and uses aluminum windings in a 916A frame; allow adequate rack or pad space and ensure ventilation. Consider WS19 weather protection for outdoor sites and verify the voltage taps (+2.5% and -2.5%) are set to match site voltage conditions.
The transformer is rated 112.5 kVA, three-phase, with a 480 V primary and 208Y/120 V secondary. It operates at 60 Hz, has a 150 °C rise with a 200 °C insulation system, and features taps at +2.5% and -2.5%. The unit is UL Listed and designed to meet NEMA TP-1 efficiency standards, with low sound output around 47 dB.
Yes. It uses a K-Factor nonlinear ventilated design intended to manage harmonic currents effectively while maintaining efficiency. This makes it well-suited for facilities with heavy variable-speed drives, SCR loads, and other harmonic sources, helping to reduce overheating and improve power quality.
The N48M28T12EELS47 is UL Listed and NEMA TP-1 compliant, with catalog notes highlighting low sound output (47 dB) and efficiency. These certifications support regulatory compliance and quieter operation in manufacturing floors, data centers, and industrial facilities.
