Eaton N48M28F3021LS42 K-Factor nonlinear transformer UL
Part Number: N48M28F3021LS42
Quick Summary
Eaton K-Factor nonlinear ventilated transformer delivers reliable power isolation for data centers, manufacturing floors, and process plants. Many facilities struggle with heat, voltage sags, and uneven load that threaten uptime and efficiency. UL Listed certification validates safety and compliance for electrical equipment, while regional requirements may call for CE or IP ratings. For engineers, this three-phase transformer integrates with standard power management systems to simplify installation and service. It also supports efficiency gains and predictable load performance critical to procurement decisions. With 30 kVA capacity and a 480-208Y/120 delta-wye configuration, it scales with expanding plant loads and minimizes voltage distortion under harmonic stress. Ventilated design further enhances cooling in cramped electrical rooms, helping maintain reliability in industrial environments.
