7.1.1 Low Voltage Power Supply Circuit
The machine’s DC power supply is generated by the power supply PCB.
The AC power arriving at the power supply PCB is converted into the following for sup-
ply to loads: +3.3 VDC, +3.3 VSDC, +5 VDC, +5 VSDC, +12 VDC, +24 VDC.
See the following for an outline of the DC power supply:
