DC POWER SUPPLY CIRCUIT
The DC Power supply PWB is responsible for taking the AC voltage from the
wall outlet and converting it to the necessary DC voltages used in the various
components of the imager. AC voltage is rectified to a DC voltage and then
stepped down to the appropriate voltages necessary to operate the DC
components of the imager. The DC voltages produced the DC PWB are:
FW / 3.3VDC for the ICU PWB / 5VDC for logic, laser unit, and sensors
/ 12VDC for ID/DM sensors, CCD and HD / 24VDC for motors, clutches and
solenoids/ 38VDC for the main motor and scanner motor.
