Eaton Specification Sheet - N48M47F1216LS50
Feature: K-Factor nonlinear design improves harmonic handling, reducing overheating risk and enabling compliant operation under nonlinear loads. Business Impact: minimizes heat and energy waste while extending transformer life. Application: ideal for drives, inverters, and other nonlinear equipment in automated production lines. Feature: Aluminum windings reduce weight and improve heat dissipation compared to copper-only equivalents. Business Impact: easier installation, lower mounting stress, and potentially lower cooling costs. Application: floor or wall-mounted installations in crowded switchgear rooms. Feature: NEMA 2 enclosure provides basic protection against dust and moisture. Business Impact: fewer enclosure failures and extended service intervals. Application: dusty manufacturing floors, maintenance bays, and mixed-use facilities. Feature: Tap size 2 at +2.5%, 4 at -2.5% enables precise voltage regulation. Business Impact: tighter secondary voltage control and improved equipment performance. Application: critical automation panels and control sets requiring stable voltages. Feature: DOE 2016 compliant efficiency with 10 CFR Part 431 framing ensures regulatory alignment. Business Impact: reduced energy costs and easier compliance reporting. Application: energy-conscious facilities and regulated manufacturing environments. Feature: Electrostatic shield option reduces EMI and noise coupling into nearby control circuits. Business Impact: improved signal integrity and reliability for sensitive automation equipment. Application: control rooms and instrumentation cabinets within mixed-load environments. Feature: Sound level of 50 dB supports closer installation to office or lab spaces. Business Impact: lower acoustic footprint and less noise-related downtime. Application: plant perimeter rooms, data centers, and automated test bays.
