NOTES
BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
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 a 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 specifications.
7. The ON/OFF control pin voltage is referenced to -Vin.
To order positive logic ON-OFF control add the suffix P (Ex: DM48S5-3000P)
To order negative logic ON-OFF control add the suffix R (Ex: DM48S5-3000R)
8. Heat sink is optional, consult factory.
9. The DM Series can meet EN55022 Class A with an external capacitor in parallel with the input pins.
Recommended: 12Vin: 6.8µF/50V 24Vin: 2.2µF/50V 48Vin: 1.5µF/100V
10.
An external filter capacitor is required if the module has to meet EN61000-4-5. The filter capacitor Wall Industries suggests: Nippon chemi-con
KY Series 220uF/100V ESR 48mΩ.
