Official Power Requirements for Onefinity

The DC output of the Meanwell power supply is 9.7A. This is not equivalent to the AC input current. To calculate the maximum AC input current you also have to take into account the efficiency of the power conversion. Long story short, the maximum AC input current is typically 3.44A at full load.

This does not take into consideration of the vacuum and router/spindle that require much more power. These should be on separate circuits than the controller and screen.
