When the output current is: >4 A: DSF100, >7.77 A : DSF200LV >28 A: DSF500 then the INH pin is pulled logic low. This can be used to inhibit downstream DC-DC converters and reduce the load on the filter. When the output current is lower than above the INH pin is logic high. * Shuts down output by pulling disable pin low when baseplate >100 C.

For input voltages above 18 V, maximum load is 500 W. 2. FSO461 has filter circuitry only. To be used with DSF500 for conducted immunity compliance. 3. DSF500 has surge protection only. To meet stated EMC performance it must be used with FSO461.
