Fuse for parallel AC/DC power supply
This is supplementary to spadeANDarcher's answer, as there is something in the question which isn't asked.

Please see Connecting two power supplies with same voltage rating to increase current output? to read why connecting the two Meanwell PSU outputs in parallel may lead to failure.

However, as you have two major current draws, you could supply each from one of the PSUs and connect only the grounds of the PSUs. The rest of the electronics can be supplied from just one of the PSUs, assuming its current rating is not exceeeded:

[Apologies for the hairy components.]

You could even have provision on the PCB to connect the "OtherElectronics" to the other PSU so that if the one it is connected to fails then it can use the other PSU, although the VFDs on the failed PSU will of course not be powered.
