FAQs
mounting the N48M28F22CU requires a sturdy base capable of supporting its 1963 lb weight, with clearances for cooling and wire access. Use the 918A frame and compatible enclosure, ensure ventilation for the 115°C rise, and verify ambient conditions meet the product's specification. Plan for copper wiring and shield connections to minimize EMI and maintain electrical safety clearances.
The N48M28F22CU is a 225 kVA, three-phase transformer with a 480 V primary and 208Y/120 V secondary. It operates at 60 Hz and features taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling voltage adjustments to cope with supply fluctuations. Copper windings and electrostatic shielding support efficiency and EMI management.
Yes. With a 225 kVA rating, 480 V to 208Y/120 V conversion, and K-Factor nonlinear design, it is well-suited for data centers, manufacturing floors, and factory automation where nonlinear loads and harmonic concerns are present. The UL Listed certification further supports compliance in safety-conscious facilities, while the WS34 weather shield enables versatile outdoor or harsh-environment installations.
The N48M28F22CU carries UL Listed certification, indicating compliance with recognized safety standards for electrical equipment. This certification helps streamline procurement for regulated facilities and reduces risk during commissioning. Note that other certifications such as SIL, CE, or IP ratings are not listed for this model in the provided data, so verify specific regulatory requirements with your procurement team if those are necessary.
Maintenance benefits include robust copper windings, electrostatic shielding, and a high-temperature rise rating (115°C), promoting reliability under load. The transformer’s scalable 225 kVA rating, reliable 60 Hz operation, and weather protection reduce downtime and spare-part costs, delivering a favorable total cost of ownership for data centers and automated facilities where uptime and power quality are critical.
