Hammond Power Solutions DM145BK is a three-phase general duty transformer designed for voltage transformation in industrial power distribution systems. It converts a 208V delta primary to a 480Y/277V wye secondary, rated at 145 kVA with 60Hz frequency and 3-6% impedance, featuring aluminum windings with a 150°C temperature rise and 220°C insulation class. The unit is housed in a Type 3R / IP24 enclosure with an ANSI 61 grey finish, measuring 41" H × 32" W × 25.5" D, weighing 820 lb, and operating at 50 dBA sound levels. It is certified to CSA and UL standards and complies with IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5). Typical applications include industrial facilities, commercial buildings, and outdoor power distribution systems requiring reliable voltage step-up with weather protection.
