Overview

The Hammond Power Solutions DM075KK is a 75 kVA, three-phase drive isolation transformer engineered for variable speed drive applications, ensuring optimal performance in industrial environments. This unit delivers a 480V Delta primary and a 480V secondary winding configuration, providing critical voltage isolation between AC/DC drives and motor systems while preserving phase integrity. Constructed with high-quality aluminum windings, the DM075KK enhances durability and thermal efficiency, reducing energy losses and extending operational lifespan. Compliant with UL and CSA standards, the transformer guarantees reliable and safe operation in demanding industrial settings. With a 75 kVA capacity, it supports drive systems up to 50 HP, making it suitable for mid-range applications. The HPS Tribune series transformer is designed for energy efficiency and low harmonic distortion, serving as an ideal interface for variable frequency drives (VFDs), motors, and generators. Standard voltage options include 240V, 380V, and 600V for both primary and secondary configurations, with custom voltages available to meet specific application requirements. The DM075KK is manufactured in the USA, ensuring consistent quality and adherence to stringent production standards.
  • 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.
  • Drive Isolation Transformers are sized to match standard motor horsepower and voltage ratings. Standard sizes range from 5 to 600 HP in six standard voltages.
  • UL and CSA compliant for safety and reliability
  • Suitable for variable speed drive applications up to 50 HP
