| Notes & safety | |
| Notes: | 1. MTBF: BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C. (Ground fixed and controlled environment). 2. 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. 3. 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). 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. |
