APPLICATIONS

TheIF_S-2WSeriesarespeciallydesignedforapplications whereagroupofpolarpowersuppliesareisolatedfromthe inputpowersupplyinadistributedpowersupplysystemona circuitboard. Theseproductsapplyto: 1)Wherethevoltageoftheinputpowersupplyisfixed (voltagevariation ≤±5%); 2) Whereisolationisnecessarybetweeninputandoutput (isolationvoltage ≤3000VDC); 3)Wheretheregulationoftheoutputvoltageandtheoutput ripplenoisearedemanded.
