Power Supply Assembly
Power supply schematic diagram is shown below.
This equipment receives 5 systems (24
.5,
24, 6, 5, 4.5 V) of power supply from the reader
unit.
24V is mainly used for the motor, the solenoid, the fan, and the LED lamp unit.
5V is mainly used for the sensor.
The converter in the DADF driver PCB (PCB1) generates 3.3V, and supplies to the original
width volume (VR).
