Application Note
Remote ON/OFF Control
Derating
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).
The operating case temperature range of the CHB100/150 series is -40˚C to +100˚C. When operating the CHB100/150 series,
proper derating or cooling is needed .
