## **Notes:** 

1.  Unless otherwise specified, parameters in this datasheet were measured under the conditions of Ta=25°C, humidity<75%RH with nominal input voltage and rated output load; 

2. The ambient temperature derating of 5°C/1000m is needed for operating altitude greater than 2000m; 

3. All index testing methods in this datasheet are based on our company corporate standards; 

4.  In order to improve the efficiency at light load, there will be audible noise generated, but it does not affect product performance and reliability; 

5. We can provide product customization service, please contact our technicians directly for specific information; 

6. Products are related to laws and regulations: see “Features” and “EMC”; 

7. The out case needs to be connected to PE ( ) of system when the terminal equipment in operating; 

8. Warning: Use double fuses, please disconnect the power before maintenance and replacement; 

9.  Our products shall be classified according to ISO14001 and related environmental laws and regulations, and shall be handled by qualified units. 

10.  The power supply is considered a component which will be installed into a final equipment. All EMC tests should be confirmed with the final equipment. Please consult our FAE for EMC test operation instructions.
