As Power Supplies Australia mentioned in a previous blog post about MEAN WELL Power Supply’s Hiccup Mode, not all power supplies within the same series will have the same method of short circuit protection.
In our opinion the best power supply manufacturer is MEAN WELL. It is no accident that the majority of power supplies we offer are MEAN WELL power supplies.
Depending on the age of your MEAN WELL Multi-Rail power supply, you may need to ensure all outputs have a load that falls within the stipulated current range shown in the data sheet.
