CMDM

The CMDM series of chassis mount dc/dc converters are single output modules with up to 15 watts of output power. This series is designed for a 2:1 input voltage range of 9VDC-18VDC, 18VDC-36VDC, or 36VDC-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.

● 15 Watts Output Power ● Output Current up to 4A ● High Efficiency up to 88% ● Fixed Switching Frequency ● Six-Sided Continuous Shield ● 2:1 Wide Input Voltage Range ● ISO9001 Certified Manufacturing Facilities ● Call Factory for More Output Power Options ● Compliant to RoHS EU Directive 2002/95/EC ● Options: Positive Logic and Negative Logic Remote ON/OFF ● Chassis Mount Options: Open Frame, U Channel, and Enclosed Types Available

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).
Due to advances in technology, specifications are subject to change without notice.
Safety Approvals: IEC60950-1, UL60950-1, EN60950-1
RoHS Compliance: Yes
