DM034NJ - Hammond Power Solutions 34kVA 575-460 3PH Drive Isolation Transformer

DM034NJ

DM034NJ is a three-phase drive isolation transformer rated at 34 kVA, designed to meet the demanding requirements of AC and DC variable speed drives while providing electrical isolation between incoming line and SCR load. DM034NJ features a primary voltage of 575 delta, secondary voltage of 460Y/266 wye-neutral, and aluminum construction with a 220°C insulation system and 150°C temperature rise. The transformer windings are engineered to withstand overcurrent of 150% of rated load for 60 seconds or 200% of rated load for 30 seconds, making it suitable for harsh industrial environments.
