Overview

The Hammond Power DM118BK is a 1.2kV class, three-phase drive isolation transformer (DIT) rated at 118 kVA. Designed for variable speed drives (VSDs) and motor control applications, this dry-type transformer features robust aluminum windings for efficient power transfer and durability. It operates within a primary voltage range of 208–480V, making it compatible with a wide range of industrial power systems. The DM118BK isolates drive loads from the power source, reducing harmonic distortion and electrical noise to protect sensitive control systems. Built to ANSI C57.12.01/NEMA ST-20 standards, it meets UL 1561, CSA C9, and CA 22.2 No. 47 requirements. Ideal for applications requiring stable, clean power delivery to AC or DC motor drives, this transformer ensures consistent operational performance and extended equipment lifespan. Suitable for use in industrial facilities, manufacturing plants, and commercial buildings where variable speed drives are employed.
  • The separate primary and secondary windings provide electrical isolation between the incoming line and the SCR load.
  • Designed to reduce harmonic distortion and electrical noise
  • Meets ANSI C57.12.01/NEMA ST-20, UL 1561, CSA C9, and CA 22.2 No. 47 standards
