Series LF/LM

75W Isolated Regulated High Power DC-DC Converter

The LF/LM series are isolated DC-DC converters with a wide selection of input voltage ranges from 18V to 380V in a compact half brick size foot print – 2.4″ x 2.3″. These modules have trim capability and shutdown features. Protections include input overvoltage, output short-circuit, output overvoltage and over temperature.

The unique case has integrated side heat sink for better thermal dissipation but is capable of conduction cooling through the baseplate or additional top mounted heat sink.
