Hammond Power Solutions DM075KDS - 75 kVA Transformer 480D-240Y/139V (Type 3R)

DM075KDS

Hammond Power Solutions DM075KDS is a 75 kVA three-phase general duty transformer designed for industrial power distribution applications. This unit features a 480V delta primary configuration stepping down to 240Y/139V wye-n secondary with 60Hz frequency and 3-6% impedance, constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 38x26x21 inches, producing only 50 dBA sound levels while meeting IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5). Compliant with UL50 standards and approved for installation in US and LATAM markets, this transformer employs mechanical lug terminations with standard 5% FCAN taps and Dyn1 vector configuration for reliable operation in manufacturing facilities, industrial plants, and commercial power systems.
