FAQs
Yes. The N48M28T4521CUI3 is a three-phase transformer rated at 45 kVA and configured for 480-208Y/120 input/output. Its footprint (24 in L × 30.5 in W × 36.88 in H) and weight (658 lb) support straightforward floor mounting and rack or pad installations. Ensure adequate ventilation and clearances per UL guidelines.
The K-Factor nonlinear design (K13) mitigates harmonic currents, reducing voltage distortion and transformer overheating under non-linear loading. This improves reliability, extends insulation life, and lowers energy losses in equipment like drives and power supplies. It is particularly valuable in data centers and manufacturing lines with high harmonic content.
Best suited for data centers, manufacturing floors, and process plants requiring stable three-phase power with harmonic mitigation. The 45 kVA rating supports medium-density feeders, while the vented XFMR design helps manage heat in cabinets with limited cooling. Its high safety standard (UL Listed) also makes it attractive for regulated industrial environments.
The product is UL Listed, signaling conformance to recognized safety standards for electrical equipment. This helps with compliance during commissioning, reduces risk during audits, and supports safer installation, maintenance, and operation across multiple regions where UL recognition aligns with local electrical codes.
Maintenance concerns focus on ensuring proper ventilation and clean cooling paths to sustain heat dissipation. The vented design reduces overheating risk under heavy loads, which lowers failure rates and extends service life. ROI is driven by improved uptime, reduced energy losses due to efficient operation, and lower risk of costly downtime in critical automation and manufacturing processes.
