Output Module Inhibit (INH)
|
|
DSF200: When the output >7.77 A, then the INH pin is low. When the output <7.77 A, then the INH pin is logic high. DSF500: When the output current is >28 A, then the INH pin is low. When the output current is <28 A then the INH pin is logic high.

|
Overtemperature Protection
|
|
Shuts down output by pulling disable pin low when baseplate > 100 ºC. Typical hysterisis 5 ºC auto recovery (not fitted to ‘-H’ models)
