PI Type OUTPUT SPECIFICATIONS: Application Note Derating The operating case temperature range of the CHB100/150 series is -40C to +100C. When operating the CHB100/150 series, proper derating or cooling is needed . Following is the derating curve of CHB100/150 without heat sink. Remote ON/OFF Control The CHB100/150 Series allows the user to switch the module on and off electronically with remote on/off feature. The CHB100/150 Series are available with "positive logic" or "negative logic" (option).
