| 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). 6. This product is Listed to applicable standards and requirements by UL. Due to advances in technology, specifications are subject to change without notice. |
