Overview

The Hammond Power DM330KKC is a 330 kVA drive isolation transformer engineered for AC and DC variable speed drives. This three-phase transformer delivers 480V input to 480V output, ensuring compatibility with standard industrial power systems. Constructed with high-quality copper windings, it provides reliable power transfer and efficient voltage transformation for sensitive drive applications. The unit features a ventilated, convection air-cooled design with a single 3-leg core and three coils, meeting UL, CSA, and NEMA standards. Designed for non-linear load applications, it is de-rated per ANSI/IEEE C57.110 for optimal performance. The NEMA 3R outdoor-rated enclosure protects against environmental factors, making it suitable for indoor and outdoor installations. With a 10-year limited warranty, the DM330KKC ensures long-term durability and operational stability in demanding industrial environments.
  • 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.
  • Ventilated, convection air-cooled design with single 3-leg core
  • NEMA 3R outdoor-rated enclosure for indoor/outdoor use
