Centroid Community CNC Support Forum

I am in the process of putting all of my CNC components in an enclosure. In the enclosure I have 3 separate ABB power supplies 5V, 12V, and 24V. What I would like to do is connect the oak board to these power supplies and no longer use the mean-well. However upon disconnecting it I quickly grew confused on how to make some of the connections. I have listed the pins below. Each power supply has a + and - terminal. What I think I understand is from the H1 connector pin 1 goes to 12v power supply +, pin 2 ????, pin 3 12 power supply-, pin 4 5V power supply+, pin 5 ???? Possibly 5V power supply -, pin 6 goes to earth ground, please let me know what you guys think. Any advice will be greatly appreciated.

Pin 1: +V2(12V)
Pin 2: COM (12V COM)
Pin 3: -V4 (-12V)
Pin 4: +5V
Pin 5: COM (5V)
Pin 6: ACG (AC GROUND)

Thank you
Robbie

I suggest just keeping the Meanwell supply. It helps separate the controller from EMI and noise generated from other devices connected to your supplies. If you really want to replace the Meanwell, you'll need to add a -12V supply to your system.

Tblough,

Thank you for the advice, I will reconnect the mean-well power supply.

Don't use the Meanwell Logic power supply for anything else. Follow the schematic.
Contactors would use a separate power supply, solenoids etc.
