| Notes & safety | |
| Notes: | 1. The CMJR Series requires a minimum 10% 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. 2. The ON/OFF control pin voltage is referenced to -Vin. To order negative logic On/Off control add the suffix "-R" (Ex: CMJR5S5-2000-R). 3. MTBF: BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C. (Ground fixed and controlled environment). 4. "I" Version is more efficient therefore, it can be operated over a more extensive temperature range than the standard version. Please add the suffix "-I" for industrial grade temperature range models. 5. Heat sink is optional, please consult factory for ordering details. 6. 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). 7. This product is Listed to applicable standards and requirements by UL. Due to advances in technology, specifications are subject to change without notice. |
| Safety Approvals: | IEC60950-1, UL60950-1, EN60950-1 (except for 5V input models) |
