I phrased my comment poorly, which mislead you. I was suggesting a UPS which took 208VAC on on the charge side, and charged 48VDC batteries with it, providing -48 to a rack full of equipment which took that.
People actually call those "48VDC UPSs", though in fact they're just Little Teeny Battery Plants. :-)
Ah, well, the XW (6048's) *do* have a 100A charger each (so up to 300A @ ~48VDC) so they could be used for that too :D-- but that same industry segment, solar/renewable, makes 48VDC charger only/rectifier only systems as well. So my answer still sort of stands :D
