CMJR

The CMJR series of high efficiency chassis mount dc/dc converters are single output modules with up to 10 watts of output power. This series is designed for a 2:1 input range of 4.5-9VDC, 9-18VDC, 18-36VDC or 36-75VDC. Some features include 1600VDC I/O isolation, positive or negative remote on/off, and short circuit, over load, and over voltage protection. Chassis mounts come in open frame, U channel, and enclosed types.

● 10 Watts Output Power ● High Efficiency up to 86% ● Fixed Switching Frequency ● Six-Sided Continuous Shield ● 2:1 Wide Input Voltage Range ● International Safety Standard Approval ● Call Factory for More Output Power Options ● Options: Add suffix “-I” for Extended Operating Temperature Range ● Chassis Mount Options: Open Frame, U Channel, and Enclosed Types Available

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).
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)
