Overview

The Hammond Power DM145JH Drive Isolation Transformer (DIT) is a three-phase, 145 kVA unit designed for AC and DC variable speed drives. It provides voltage transformation from 460V to 400V, ensuring compatibility with industrial motor control systems. The transformer features aluminum windings for lightweight durability and efficient heat dissipation, making it ideal for high-performance applications in manufacturing, HVAC, and renewable energy systems. Key specifications include a 145 kVA rating, 460V primary input, and 400V secondary output, supporting three-phase operation. Its isolation design reduces harmonic distortion and protects sensitive equipment from voltage spikes, extending the lifespan of connected drives and motors. The aluminum construction reduces weight compared to copper alternatives while maintaining high thermal conductivity. Applications include variable frequency drives (VFDs), servo systems, and industrial automation where precise voltage regulation and electrical isolation are critical. The DM145JH meets rugged industrial demands with compact dimensions optimized for panel mounting or standalone installations.
  • 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.
  • Reduces harmonic distortion and protects sensitive equipment
  • Compact design for panel or standalone mounting
