1. All parameters NOT specially mentioned are measured at 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.
