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 of standard type.
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 ON/OFF control pin voltage is referenced to -Vin.
To order positive logic ON-OFF control add the suffix “P” (Ex: CMKR48S5-1000P)
To order negative logic ON-OFF control add the suffix “R” (Ex: CMKR48S5-1000R)
7. The industrial “I” suffix for the 2:1 input version is more efficient; therefore, it can be operated in a more extensive
temperature range than “standard” and “I” suffix 4:1 input versions.
To order industrial temperature range (-40°C ~ +85°C) add the suffix “I” to the part number (Ex: CMKR48S5-1000I)
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.
