60-70v unregulated power supply recommendations

Hi Neale

The other variable is when an axis decelerates and the motors becomes generators returning energy back to the power supply capacitors

the voltage at power supply terminals could be increased beyond the drivers limit
if the decelerating axis returns a lot more energy than other axis use and the power supply capacitors can absorb

Hi Joe
the great thing with the 625VA transformers with Bifilar wound 45V secondaries is they can be connected in parallel to give you 45V at 13.88A
you just get the phasing of the winding correct !!!
