Eaton V48M28T45NV Transformer - DT-3 Dry Type
Part Number: V48M28T45NV
Quick Summary
V48M28T45NV transformer provides reliable three-phase power distribution for industrial control systems in manufacturing facilities. Too often, heat buildup and voltage drift from undersized or poorly cooled units drive downtime and maintenance costs. This Eaton design solves those issues with a totally enclosed non-ventilated enclosure, aluminum windings, and a DT-3 frame engineered for rugged service. UL Listed certification supports safety compliance, while a 150°C rise rating accommodates demanding environments. With two primary taps at +2.5% and four at -2.5%, plus a 208Y/120V secondary, this transformer offers flexible voltage regulation and straightforward panel integration. For engineers and procurement teams, the combination of reliability, installability, and long-term performance translates into lower lifecycle costs and fewer field surprises.
