Hammond Power Solutions DM275JH is a 275 kVA drive isolation transformer designed to provide electrical isolation between the incoming line and the SCR load in industrial power systems. It operates with a 460 VAC primary voltage and a 400Y/231 VAC secondary voltage in a three-phase configuration at 60 Hz, featuring aluminum windings with a 220°C insulation system and the ability to withstand overcurrent conditions of 150% rated load for 60 seconds or 200% for 30 seconds. The unit is housed in a Type 3R / IP24 enclosure with an ANSI 61 UL 50 gray finish for indoor/outdoor use, includes lug/pad type connections for floor mounting, and is equipped with a coil-mounted thermal warning switch. It is certified to CSA and UL standards. This transformer is suited for industrial applications requiring reliable power conversion and isolation.
