DESCRIPTION
The CR series of DC/DC power converters provides 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 compliant and have UL60950-1, EN60950-1, and IEC60950-1 safety approvals. This series is best
suited for use in wireless networks, telecom/datacom, industry control systems, semiconductor
equipment, and distributed power architectures.
Applications:
• Wireless Networks
• Telecom/Datacom
• Industry Control Systems
• Distributed Power Architectures
• Semiconductor Equipment

NOTES
1. The CR series can only meet EMI Class A or Class B with external components added. Please contact factory for more information.
2. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. For 12VDC nominal input models we recommend
connecting an aluminum electrolytic capacitor (Nippon chemi-con KY series, 220µF/100V) and a TVS (SMDJ58A, 58V, 3000 Watt peak pulse power)
diode in parallel. For 24VDC nominal input models we recommend connecting an aluminum electrolytic capacitor (Nippon chemi-con KY series,
220µF/100V) and a TVS (SMDJ64A, 64V, 3000 Watt peak pulse power) diode in parallel. For 48VDC nominal input models we recommend connecting
an aluminum electrolytic capacitor (Nippon chemi-con KY
connected in parallel.
series, 220µF/100V) and a TVS (SMDJ120A, 120V, 3000 Watt peak pulse power) diode
3. Both positive logic and negative logic remote ON/OFF control is available. Positive logic remote ON/OFF comes standard; for negative logic remote
ON/OFF add the suffix “R” to the model number (Ex: CR48S05-40R).
4. Optional heatsink is available. Please call factory for ordering details.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
Due to advances in technology, specifications subject to change without notice.
