Notes & safety
Notes: 1. Add “C” to model number to indicate terminal with protective cover, and “Q” to model number for conformal coating.
2. Minimum load: when the product is working at a temperature above 50°C the minimum load is 5% of the rated load, so that the fan could work at high temperature to reduce the temperature rise of the product.
3. Tip and barrel method is used for ripple and noise test. Output parallel 47uF electrolytic capacitor and 0.1uF ceramic capacitor, contact factory for more information.
4. Over-Current Protection: test at rated output voltage. Io is rated output current load.
5. Over-Temperature Protection needs to be tested under rated full load conditions.
6. This product is Listed to applicable standards and requirements by UL.
7. One magnetic bead (nickel-zinc ferrite) should be coupled with the output load line during CE/RE testing.
8. The power supply is considered a component as part of a system. All EMC items are tested on a metal plate (450mm x 450mm x 3mm). Power supply should be combined with final equipment for EMC confirmation.
9. Ambient temperature derating of 5°C/1000m is needed for operating altitude greater than 2000m.
10. In order to improve the efficiency at high input voltage, there will be audible noise generated, but does not affect product performance and reliability.
11. Product customization service is available, please contact factory for more details.
12. Out case needs to be connected to PE ( ) of system when terminal equipment in operating.
13. Output voltage can be adjusted by the ADJ, clockwise to decrease
14. Products should be classified according to ISO14001 and related environmental laws and regulations and should be handled by qualified.
15. Power supply is considered a component which will be installed into terminal equipment. All EMC tests should be confirmed with final equipment.
Safety Approvals: IEC/EN/UL62368/GB4943
