Maybe something like this (I wonder if they make it themselves or OEM it):

500 watts is a lot of power.  I would probably just split the loads between two 
Mean Well RSDs, or use a small DIN rail converter for each load, or set up a 
second battery string (I assume you need both +48 and-48?).  If I was running 
that much off a DC-DC converter, I would probably want N+1 redundancy.

You can always get a DC inverter, make 120 VAC, then feed a DC power supply.  
Any wattage you need any voltage you need.  Just mix and match.

Hey Guys 

WE are needing a higher capacity DC-DC converter (500 watts) Redundant if 
possible. 

Meanwell RSD only go up to 300 watts... 

Any ideas?
