Converters in universal power supplies tend to fail around 75-85Vdc even at low loads and usually can't deliver full current at 90Vac, in my experience (was using universal power supplies in electric cars; okay for 96V+ cars, but unusuable for 72V and below). 48Vdc is not a reasonable expectation, unfortunately.
