I use PM752 supplied with 65VDC. Transformer is 500watt.

And the beakout board you use is pcpps from zapp automation? Because in the manuals for this board is written that it supports only max 35V? But the board is using the same voltage as drivers?

Please see 1st picture on my website - Control box http://malamuterun.co.uk/cnc/homemade_cnc_mill.htm
There is two power sources.
1. Toroidal transformer with 25Abridge and capacitor at the top for PM752.
2. 25V power supply at the bottom for PCPPS-3 from zapp.
Two power suppliers share ground/negative.
