Input Reverse Voltage• Continuous Protection Fuse Protection • External T25 A fuse is recommended Output Output Voltage • Tracks input voltage & clamps <36 VDC Output Power • 200 W max Thermal Warning (TW)• The TW output is an open collector transistor rated at 100 VDC, with a maximum sink current of 10 mA, referenced to –V in/-V out. The signal output is low when the maximum base plate temperature is exceeded. This signal indicates an over temperature condition so that action can be taken by the end application such as shutting down non critical loads or individual downstream DC/DC converters. If connected to the DIS pin of the DSF226 this will disable the filter output and perform as a thermal shut down for the system. The TW output will automatically return to a high signal level once the filter base plate has cooled to a temperature of less than 100°C. Maximum Output • 10,000 µF recommended Capacitor Specification Filter & Surge Protection
