Typical value at nominal input voltage and full load. Test by minimum Vin and constant resistive load. The ON/OFF control pin voltage is referenced to -Vin. To order negative logic ON/OFF control add the suffix ”R” (Ex: MDW48S5-4000R) Heat sink is optional, consult factory for ordering details. The MDW Series can meet EN55022 Class A with an external capacitor in parallel with the input pins. Recommended: 24Vin: NA. 48Vin: 1µF/100V An external filter capacitor is required if the module has to meet EN61000-4-5.
