FAQs
The N48M28F5016CU is a three-phase transformer with a 480 V primary and 208Y/120 V secondary. It is designed for floor or wall upright mounting in industrial spaces and uses a 283B wiring configuration. Ensure proper clearance, cooling, and protective enclosures (NEMA 2) per Eaton installation guidelines to achieve rated performance.
DOE 2016 efficiency compliance reduces load and no-load losses, lowering energy consumption over the life of the unit. UL Listing confirms compliance with safety standards, plus 10 CFR Part 431 notes, helping with regulatory approvals and warranty coverage during procurement.
Yes. The N48M28F5016CU features a K-Factor of 13, indicating robust performance under harmonic loads. This reduces overheating and maintains voltage quality when drives, welders, or other non-linear equipment are present.
The transformer offers 2 taps at +2.5% and 4 taps at -2.5%, enabling fine voltage regulation to compensate for line drops or fluctuations. Properly configuring taps helps maintain consistent secondary voltage, protecting sensitive controls.
Copper windings and 220 °C insulation support long service life and efficient operation, reducing maintenance needs. DOE efficiency and shielded construction also lower cooling loads and EMI concerns, contributing to lower total cost of ownership in rigorous manufacturing environments.
