CMDD

The CMDD series of chassis mount DC/DC converters are single output modules with up to 60 watts of output power. This product is ideal for telecommunications, industrial, mobile telecom and test equipment applications. These converters are designed for a 2:1 input voltage range of 18VDC-36VDC or 36VDC-75VDC. Some features include 1600VDC isolation, remote on/off, and output adjustability. All models are short circuit, over load, and over voltage protected. Chassis mounts come in open frame, U channel, and enclosed types.

● Single Output Up to 14A ● High Efficiency up to 91% ● RoHS Directive Compliant ● Fixed Switching Frequency ● No Minimum Load Required ● Approved for Basic Insulation ● 2:1 Wide Input Voltage Range ● 60 Watts Maximum Output power ● Call Factory for More Output Power Options ● Chassis Mount Options: Open Frame, U Channel, and Enclosed Types Available

Notes & safety
Notes: 1. The ON/OFF control function: There are positive (standard) and negative logic (option). The pin voltage is referenced to negative input. To order negative logic ON/OFF control add the suffix "R" to the part number (Ex: CMDD48S5-12000R).
2. MTBF: BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40°C. (Ground fixed and controlled environment). MIL-STD-217F Notice2 @ Ta=25°C, Full Load (Ground, Benign, controlled environment).
3. Heat sink is optional. Please call factory for ordering details.
4. 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).
5. The "Sense" option is not available for this series.
Due to advances in technology, specifications are subject to change without notice.
