Note
1. 2. 3. The FEC15 series required a minimum 10% 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 Please add an external filter at converter input terminals when measuring input reflected ripple, as figure 1. L: Simulated source impedance of 12H C: Nippon chemi-con KMF series 100F/100V The ON/OFF control is option function. There are positive logic and negative logic. The pin voltage is referenced to negative input To order positive logic ON-OFF control add the suffix-P (Ex: FEC15-24S05-P) To order negative logic ON-OFF control add the suffix-N (Ex: FEC15-24S05-N) BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40C. (Ground fixed and controlled environment) Heat sink is optional and P/N: 7G-0020A Maximum value at nominal input voltage and full load Typical value at nominal input voltage and full load Test by minimum Vin and constant resistive load.
