DESCRIPTION
The CRW 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 4:1 ultra
wide input voltage ranges of 9-36VDC, 18-75VDC, and 43-160VDC. 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, industry control systems, telecom/datacom, semiconductor equipment,
distributed power architectures, and railway systems.

NOTES
1. The CRW 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 24VDC nominal input models we recommend connecting an aluminum electrolytic capacitor (Nippon chemi-con KY series, 330µF/50V) in parallel.
For 48VDC nominal input models we recommend connecting an aluminum electrolytic capacitor (Nippon chemi-con KY series, 220µF/100V) in parallel.
For 110VDC nominal input models we recommend connecting three aluminum electrolytic capacitors (Ruby-con BXF series, 68µF/200V connected) in
parallel.
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: CRW48S05-40R).
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.
