It was only one module.  It has dual outputs-
one +48 Volts, one -48 Volts with a "common" betweem them.
Since the outputs are isolated from the input voltage,
I could connect the -48V to ground, the +48V to B+
and leave the "common" floating.  The result is +96V for B+.

Modules with such high votage output are scarce.  
But those that will supply + and - 15 Volts show up a lot.
Since the outputs are isolated ( important to be sure of that),
these outputs can be "stacked" just like 30Volt batteries.
I've run them like this for hours with no problems.
There are some +/- 15V on the Bay now, but the sellers
have inflated ideas about the value of surplus parts.
Units with realistic prices do appear- just have to keep
watching for them.
