Notes & safety
Notes: 1. MTBF: BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C. (Ground fixed and controlled environment).
2. 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).
3. 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).
4. Heat sink is optional, consult factory.
5. Chassis Mount Options: No suffix for open frame, "U" suffix for U Channel (add $10.00 to the listed price), and "E" suffix for Enclosed type (add $17.00 to the listed price).
Due to advances in technology, specifications are subject to change without notice.
