1. All parameters NOT specially mentioned are measured at 12,24,48VDC input, rated load and 25 of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 1uf ceramic & 10uf tantalum capacitor across output.

3. The power supply need to connect "+Vout" to "+R.S" and "-Vout" to "-R.S".

4. The power supply is considered 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.
