    4036-501 Duplex Auto Document Feeder (DADF) Power Principles of Operation The power cord carries AC line voltage to the external low voltage power supply (LVPS). The LVPS converts the 120/220VAC to regulated +5VDC, +12VDC, and +24VDC voltages. The LVPS sends these voltages to the main power switch in the Multifunction Device (MFD) controller cage.
