NOTES

1. 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: CMDBW48S5-40R)

2. 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).

3. Heat sink is optional. Please call factory for ordering details.

4. Output ripple & noise measured with a 0.1µF/50V MLCC.

5. Typical Value at nominal input voltage.

6. Maximum value at nominal input voltage and full load

7. Typical Value at nominal input voltage and full load.

8. Test by minimum Vin and constant resistive load.

9. Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type.
