HALTI –liquid cooled LC filter

Halti is the newest member of our liquid cooled LC filter family. Integrated liquid cooling concept enables the compact size of the filter. In addition, loss transfer ratio to liquid is more than 90%, which reduces filter surface temperatures and hence the air temperature in the cabinet. Typical applications for Halti are e.g. wind turbines, solar power systems and motor drives.

Compact size	Loss transfer ratio to liquid >90 %
High bandwidth operation	Minimum (10%) power loss leakage to cabinet
High switching frequency operation	Reduced filter surface temperatures
Mechanical flexibility	Improved reliability
