When operating the CHB50 , proper derating or cooling is needed . Following is the derating curve of CHB50 without heat sink. Remote ON/OFF Control The CHB50 series allows the user to switch the module on and off electronically with remote on/off feature. The CHB50 series are available with "positive logic" or "negative logic" (option).
