Here is Jeff's response from the Xylotex forum.
Hi,
The drives will only use what they need from the power supply. 8
amps will work, and will certainly be more than sufficient.
An unregualted 25.6V supply should be no problem, as the absolute
max is 35VDC, and the normal "running" max is 30VDC.
I do suggest/recommend/admonish :-) using a cooling fan blowing on
the heatsink though, when running at 25VDC and 2.5A/phase.
