Are you using the "DC OK" contacts, or you just want 2 x MOSFET

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).
I could put DC-DC converters in front of each battery plant to make it
floating but I'd rather not pile on unnecessary equipment. There has to
be something out there that works with -48V without resorting to
homebrew, I'm just not finding it.
