Power Distribution Overview
115VAC power from the wall goes into the AC box. 115VAC power (from the AC box) is routed to the
On/Off switch, and when the switch is turned on, 115VAC is routed back to the AC Power
Distribution Module. This 115VAC power, which is referred to as Switched AC (power distributed
after the On/Off switch), is sent to the DC switching power supply. The DC switching power supply
is used to create +3.3VDC, +5VDC Unswitched, +5VDC, +12VDC, +24VDC, and -12VDC. The
+12VDC and +24VDC are the primary operating potentials for the EGM. The +12VDC and +24VDC,
along with the +3.3VDC, +5VDC Unswitched, +5VDC, and -12VDC are sent to the Cabinet
Controller board for distribution throughout the rest of the EGM.
