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 internallya.
I want A and B feeds to a single-feed device (Packetflux Rackinjector).
No problem with floating power supplies for other voltages. But it won't
work in reverse because internally the (-) terminals are all tied
together and on the -48V system (-) is where the breakers are which
means then you're tying the A and B breaker outputs together (not good)
and putting the diodes on ground/return (which is useless).
What are you powering that needs negative power wrt ground?
The rectifier shelf and its batteries have return (+) bonded to ground
and breakers on (-).
