DESCRIPTION
Applications:
• Automation
• Datacom
The CR series of DC/DC power converters provides up to 40 Watts of output power in an industry
standard 2.00” x 1.00” x 0.40” package and footprint. This series has single and dual output models with
2:1 wide input voltage ranges of 9-18VDC, 18-36VDC, and 36-75VDC. Some features include high
efficiency up to 92%, 1600VDC I/O isolation, six-sided shielding, and remote ON/OFF control. These
converters are also protected against short circuit, over voltage, over load, and over temperature
conditions. All models are RoHS and REACH compliant, and have IEC/UL/EN60950-1 UL: E193009 and
IEC/UL/EN62368-1 safety approvals. This series is best suited for use in automation, telecom/datacom,
IPC, measurement, and industry control systems.
