DC Power Distribution
The +15VDC and –15 VDC lines exit the board at P11, going to the Backplane. The +15VDC provides operating power. Both are
provided through edge connector hookup to the three PCBs that reside on the Backplane.
PS2 Output
Power Supply PS2 provides operating power for the CCD camera, Image Intensifier power supply, and the Interlocks. However,
before discussing the PS2 outputs, you should understand more about the 115VAC input to PS2 as illustrated in the AC Power
Distribution diagram below. The 115VAC connects directly to PS2, as shown. However, that input goes internally direct to the T2
transformer, which is a separate FRU in the Stator system (see Stator Control, later in this manual). T2 then provides the true AC
inputs to PS2. In the next diagram, you can see those AC inputs, as well as the DC outputs.
Notice in the diagram below that all the PS2 outputs connect to the Power/Signal Interface PCB, in order to give you test points
and fuse protection for each individual main circuit. From there, all outputs except the +24 VDC supply provide the various DC
voltages needed for operation of the CCD Camera. The +24VDC supplies operating power for the Image Intensifier power supply
and the Interlocks system (see the Interlocks chapter, later in this manual.
