NOTE

1. All parameters NOT specially mentioned are measured at rated input, rated load and 25℃ of ambient temperature.

2. Measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1 uF & 47uF 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” onhttp://www.powerld.com.cn.
