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%, high 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 II & REACH compliant and have EN60950-1, UL60950-1, IEC60950-1, EN62368-1, UL62368-1, and IEC62368-1 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, 220µF/1000V) and a TVS (SMDJ58V, 3000 Watt peak pulse power) to connect in parallel.
For 48VDC 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) to connect in parallel.
For 110VDC nominal input models we recommend connecting three aluminum electrolytic capacitors (Ruby-con BXF series, 68µF/200V 3pcs in parallel) connected) (SMDJ90A, 90V, 3000 Watt peak pulse power 2pcs in series connection) to connect 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. Test by minimum input and constant resistive load. Optional heatsink is available. Please call factory for ordering details.
