Choke NTT LD-DH 100

Directly cooled surge current choke

The current limiting inductor limits the short-circuit current in a bridge circuit. Thus, the intermediate circuit is protected and prevents the destruction of the connected semiconductor devices. Usually IGBT‘s.

Advantages

  • Less copper
  • Small dimensions compared to traditional cooling methods
  • Lower weight
  • Cooling with water/glycol
  • High protection class
  • Suitable for high pulse current
