NOTES
1. Maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used, the +sense should be
connected to its corresponding +OUTPUT and likewise the -sense should be connected to its corresponding –OUTPUT.
2. The ON/OFF control function: There are positive (standard) and negative logic (option). The pin voltage is referenced to negative input.
To order negative logic ON/OFF control add the suffix “R” to the part number (Ex: DD48S5-12000R)
3. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment).
MIL-STD-217F Notice2 @ Ta=25°C, Full Load (Ground, Benign, controlled environment).
4. Heat sink is optional. Please call factory for ordering details.
5. The DD series required an external filter to meet EN55022 class A. (TBD)
6. Typical Value at nominal input voltage.
7. Maximum value at nominal input voltage and full load
8. Typical Value at nominal input voltage and full load.
9. Test by minimum Vin and constant resistive load.
