PACKING
1. All parameters NOT specially mentioned are measured at 24VDC input, rated load and 25 of ambient temperature.
2. 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.
