DESCRIPTION
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 and
IEC/UL/EN62368-1 safety approvals. This series is best suited for use in automation, telecom/datacom,
IPC, measurement, and industry control systems.

NOTES
The CR series can only meet EMI Class A or Class B with external components added. Please contact factory for more information.
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 series, 220µF/100V) and a TVS (SMDJ120A, 120V, 3000
Watt peak pulse power) 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: CR48S05-40R).
4. 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.

FUSE CONSIDERATION
This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an
integrated part of sophisticated power architecture.
To maximize flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always used an input
line fuse.
