Hammond Power Solutions DM011BK is a three-phase general duty transformer engineered for stepping down voltage in commercial and industrial power distribution systems. It operates with a 208V delta primary connection and delivers a 480Y/277V wye secondary output at 11 kVA capacity, housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish. The unit features aluminum windings with a 150°C temperature rise and 220°C insulation class, measures 21.5 inches high by 19.38 inches wide by 20.2 inches deep, and weighs 165 pounds. It is certified to CSA and UL standards, complies with IBC 2018 seismic requirements, and maintains a 45 dBA sound level per NEMA ST-20. This transformer is suited for applications requiring reliable voltage transformation with secondary terminal block connections and a YNd1 vector configuration.
