Overview

The Hammond Power DM145JJ is a three-phase drive isolation transformer (DIT) with a capacity of 145 kVA. Designed for industrial applications, this transformer features aluminum windings and operates with a primary and secondary voltage of 460 Volts. Its primary function is to isolate AC and DC variable speed drives from the power line, providing essential voltage conditioning and protection. The DM145JJ is engineered to meet the specific demands of variable speed drive systems, ensuring stable and reliable power delivery. This unit is manufactured in the USA and carries UNSPSC code 39121001. Its robust construction and precise electrical specifications make it a dependable choice for critical motor control applications where voltage stability and drive protection are paramount. The transformer's design facilitates proper operation of sensitive drive electronics by mitigating power line noise and voltage fluctuations, thereby extending the lifespan of connected equipment and preventing costly downtime. Ideal for manufacturing plants, process control systems, and any facility utilizing variable frequency drives (VFDs) or DC drives.
  • 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.
  • Aluminum windings
  • Manufactured in the USA
