Eaton Specification Sheet - N48M25F49EELS47
This transformer delivers 150 kVA at 60 Hz with a 480 V primary and a 220 delta secondary, built on a rugged 918A frame and aluminum coils. The compact footprint supports installation in power racks, switchgear enclosures, and distribution panels where space and reliability matter. With a weight of 1541 lb, it offers substantial inertia and vibration resistance, reducing mechanical wear in demanding facilities. The tap configuration—two taps at +2.5% and four taps at -2.5%—provides voltage regulation to compensate for feeder sag, ensuring downstream equipment receives steady voltage with fewer alarms and trips. The design is optimized for harmonic-rich loads thanks to K‑Factor technology, improving reliability and extending component life. UL Listed and NEMA TP‑1 efficient ratings help meet regulatory and energy-performance expectations, while low sound (47 dB) and electrostatic shielding minimize noise and EMI in crowded plant environments. The WS34 weather shield option adds outdoor resilience, enabling flexible site deployment. Overall, the combination of aluminum coil construction, robust frame, and precise taps translates to lower total cost of ownership through reduced losses, easier maintenance, and fewer field reworks during commissioning.
