Choke Ntt Ld-dh 100

Directly cooled surge current choke

DESCRIPTION

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 IGBTs.

ADVANTAGES

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