APPLICATIONS

TheIF_S-1W&IF_D-1WSeriesarespeciallydesignedforapplications whereagroupofpolarpowersuppliesareisolatedfromtheinputpower supplyinadistributedpowersupplysystemonacircuitboard. Theseproductsapplyto: 1) Wherethevoltageoftheinputpowersupplyisfixed(voltagevariation ≤±5%); 2)Whereisolationisnecessarybetweeninputandoutput(isolation voltage ≤3000VDC); 3) Wheretheregulationoftheoutputvoltageandtheoutputripplenoise aredemanded.
