Maximum value at nominal input voltage and full load. Typical value at nominal input voltage and no load. Typical value at nominal input voltage and full load. Test by minimum Vin and constant resistive load. The output requires minimum loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specification. For the single output: Maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used, the +sense should be connected to its corresponding +OUTPUT and likewise the -sense should be connected to its corresponding –OUTPUT. Load regulation for dual output : Min load to 100% load balanced on all outputs. Cross regulation for dual output : asymmetrical load 25% / 100% FL The ON/OFF pin voltage is referenced to –Vin To order negative logic ON/OFF control add the suffix-N (Ex: FEC40-24S05W-N). Heat sink is optional and P/N：7G-0026C-F. The FEC40W series can meet EN55022 Class A with parallel an external capacitor to the input pins. Recommend : 24Vin : N/A 48Vin :2.2μF/100V*2 PCS 1812 MLCC. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor Power Mate suggest: Nippon chemi-con KY series, 220μF/100V, ESR 48mΩ.
