Overview

The Hammond Power DM007JJ is a 7.5 kVA three-phase drive isolation transformer designed for variable speed AC and DC drives. Rated for 460V input and output, this transformer features aluminum windings and meets ANSI C57.12.01/NEMA ST-20 standards. Typical impedance at 60Hz ranges from 4% to 6.5%, ensuring stable power delivery for motor control systems. The transformer includes high-grade non-aging silicon steel laminations and vacuum-impregnated core and coils for durability. With a 150°C temperature rise and 220°C insulation class, it withstands harsh industrial environments. Optional taps include 1 x ±5%, 2 x ±2.5%, or 2 x +2.5%/4 x -2.5% configurations. The ventilated Type 3R enclosure is suitable for outdoor UL50 applications, finished in ANSI 61 Grey. Inrush current is limited to 10 times the full load rating, and sound levels are 3dB below NEMA ST-20 standards. Ideal for protecting sensitive drive components from line noise and voltage fluctuations, the DM007JJ extends equipment lifespan and minimizes downtime in industrial power distribution systems.
  • The separate primary and secondary windings provide electrical isolation between the incoming line and the SCR load.
  • The windings are designed to withstand overcurrent of 150% of the rated load for 60 seconds or 200% of the rated load for 30 seconds.
  • Typical impedance 4% to 6.5% at 60Hz
  • Ventilated Type 3R enclosure, ANSI 61 Grey finish
