Power supplies can be paralleled for redundancy to gain higher system availability. The unit is already equipped with a

MOSFET as decoupling device on the output to avoid, that a faulty unit becomes a load for the other power supplies

and the output voltage cannot be maintained any more.

Recommendations for building redundant power systems:

a)

Use separate input fuses for each power supply.

b)

Monitor the individual power supply units by utilizing the built-in DC-OK relay contacts on each power supply.
