Can I connect two power supplies in parallel?
In general, yes you can parallel two supplies. How well this works depends on how well they end up sharing the load current.
This depends largely on a good match in the output voltage of the supplies. If one is at 12.0 V and the other at 12.2 V, then the higher one will supply most of the current and the lower one will be idle.

We suggest applying a redundancy application to avoid power outage in case one power supply fails.

(20A redundancy application)
The ABL8RED** is normally used as a REDUNDANCY module.
So if one of the two input power supply fails, you will still supply the application because the other one will take over.

Therefore you would have to set both input power supply at the "EXACT SAME" output voltage.
This would result that when the load is consuming 20A in total, each single power supply would deliver 10A.
Only in case one of the two fails, the other one would supply the complete 20A.
