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 . ON/OFF (2) Logic State (PIN 2) Power Disspated, Pd (Watts) 25 Natural Convection 20 ft./min.
