Hammond Power Solutions DM007KK - 3-Phase Transformer 7.5kVA 480D-480Y/277V

DM007KK

Hammond Power Solutions DM007KK is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 480V delta primary configuration and delivers 480Y/277V secondary output with 7.5 kVA capacity at 60Hz frequency. Constructed with aluminum windings and housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, the transformer operates with 150°C temperature rise and 220°C insulation class while maintaining low 40 dBA sound levels. Compliant with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and approved for installation in US and LATAM markets, this transformer incorporates standard impedance ranging from 3% to 6% with Dyn1 vector configuration. Typical applications include commercial buildings, industrial facilities, and electrical distribution systems requiring reliable voltage transformation with outdoor-rated protection.
