NOTES

1. Heat sink is optional. To order the module with a heatsink please add the suffix “HS” to the model number (Ex: CBW24S12-2500HS).

2. Positive remote on/off control is standard; for negative remote on/off please add the suffix “R” to the model number (Ex: CBW24S12-

2500R).

3. Triple output models require a minimum loading on the output to maintain all specified regulations. Operation under no-load conditions

will not damage these devices; however, they may not meet all listed specifications.

4. The CBW series standard models can only meet EN55022 Class A and Class B with external components added.

5. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5.

- 24VDC nominal input models: Nippon chemi-

con KY series, 330μF/50V

- 48VDC nominal input models: Nippon chemi-

con KY series, 220μF/100V

CAUTION: This power converter is not internally fused. An input line fuse must always be used.

Due to advances in technology, specifications subject to change without notice.
