An overview of the power supply is indicated below.
With this equipment, 4 types of power (24V, 12V, 6V, and 5V) are received from the Reader Unit.
The 24V power is mainly used for the motor, solenoid, fan, and the LED Lamp Unit.
The 5V power is mostly used for the sensors.
3.3V power is generated via a converter on the ADF Driver PCB and supplied to the Original Width Volume.
