RE: [CAD_CAM_EDM_DRO] 24VDC POWER SUPPLY

The output of the dominant supply (the one with the higher output
voltage) will carry the load until it's output voltage reaches the other
supply's voltage. The second supply starts to take up the slack at that
point. If the dominant supply shut down due to current limit, the second
would also, since it would be carrying the full load.
