All Specifications Typical At Nominal Line, Full Load and 25˚C Unless Otherwise Noted. External Output Trimming Application Note Derating The operating case temperature range of the CHB75 series is -40˚C to +100˚C. When operating the CHB75 , proper derating or cooling is needed . Following is the derating curve of CHB75 without heat sink The CHB75 series allows the user to switch the module on and off electronically with remote on/off feature. The CHB75 series are available with "positive logic" or "negative logic" (option).
