Power Supply
Power Supply Route
The 24V and 5V are supplied to the puncher controller PCB through the finisher controller PCB when the host machine is turned
on.
The 5V is converted into 3.3V by the regulator IC (IC5) on the puncher controller PCB. The 24V is used to drive the motors and
the 5V is used to drive the sensors and the 3.3V is used to drive the logic.
