Hammond Power Solutions DM020JC is a three-phase general duty transformer engineered for reliable power conversion in industrial and commercial power distribution systems. This 20 kVA unit operates with a 460V delta primary connection and a 230Y/133V wye secondary output, featuring aluminum windings with a 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, weighing 230 lb, and is certified to CSA and UL standards. It complies with IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5) and operates at 45 dBA sound levels with 3-6% impedance on a 60Hz frequency. This unit is commonly deployed in commercial and industrial facilities requiring robust power conversion with a Dyn1 vector configuration.
