All parameters NOT specially mentioned are measured at 24VDC input, rated load and 25 ℃ of ambient temperature. 2. The power supply is considered a ponent 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 ponent power supplies.” (as available on http://.meanwell.) Typical Application Notes 1. 1+1 Redundancy Using 1 more PSU as the redundant unit PSU PSU 2. 1+N Redundancy: Using more PSUs as the redundant units to increase the...
