NOTES
1. BELLCORE TR-NWT-000332. Case
1:
50% Stress, Temperature
at 40ºC.
(Ground fixed and controlled environment).
2.
Maximum value at nominal input voltage and full load
3.
Typical value at nominal input voltage and no load.
4.
Typical value at nominal input voltage and full load.
5. Test by
minimum
Vin and constant resistive load.
6.
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: CMDM48S5-3000P)
To order negative logic ON/OFF control add the suffix R (Ex: CMDM48S5-3000R)
8.
Heat sink is optional, consult factory.
9.
Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type.
10.
This product is Listed to applicable standards and requirements by UL.
