NOTE 

1. All parameters NOT specially mentioned are measured at rated input, rated load and 25°C of ambient temperature. 
2. Measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1 uF & 10uF parallel capacitor. 
3. The power supply is considered as a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies” on MEPOS' website.
