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%,
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.

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.
5. This product is Listed to applicable standards and requirements by UL.
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.
