Are you using the "DC OK" contacts, or you just want 2 x MOSFET "diodes" in a 
DIN rail box?  If the schematic diagram on the Mean Well datasheet is to be 
taken literally, you could just hook it up backwards.  (reverse IN and OUT)  It 
looks like the two diodes aren't connected together internally.

What are you powering that needs negative power wrt ground?

I only need 10A, I think that's a max a Rackinjector can handle per input.

I've been trying to google such a device to death and keep coming up empty 
handed.
