Is that with nothing connected to the power supply?

The power supply has two outputs, +5VDC and +24VDC. Disconnect everything from the power supply except L, N, and Ground. What is the 5V output reading? What is the 24V output reading?
Cheers,

Did you try to adjust the voltage? There is a white adjusting knob in it.

If you have everything else still disconnected, I would go through and verify all the connections with a multimeter. That should catch a potential wiring mistake that may have killed the MeanWell and at the very least give some peace of mind. It is also possible it was an uncommon random failure.

I did redo all the connections I actually think the power supply was a little on the weak side as so of the problems I had ongoing are now cleared up. Such as not always starting up and the limits not always working.
