Overview

The Hammond Power DM075KDC is a 75 kVA three-phase drive isolation transformer designed for rugged industrial applications. Built with copper windings, it delivers reliable performance for both AC and DC variable speed drives, ensuring voltage compatibility and harmonic mitigation. The transformer supports primary voltages of 480V (delta) and secondary voltages of 240V (wye), making it ideal for VFD systems and motor control applications. With a compact footprint and floor/wall mounting options, the DM075KDC integrates seamlessly into existing electrical panels or dedicated enclosures. Its robust construction meets the demands of harsh environments, providing long-term durability and energy efficiency. Compatible with standard 60Hz systems, this transformer is a cost-effective solution for reducing voltage distortion and protecting sensitive drive components. Manufactured in the US, it carries the HPS Tribune series designation for industrial-grade reliability.
  • 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.
  • Suitable for AC and DC variable speed drives
  • Floor or wall mounting options for flexible installation
