Application Note
Remote ON/OFF Control
Derating
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).
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 .
