Project: Double Header 3 Step 3 - Power Systems

As with everything else in DH3 the power system had to be modified extensively to be functional, yet save and robust to handle 2 PSU's.   Below was a sketch I did way back in the beginning days of planning this system.  in many ways it stayed like that. But in many ways it changed:

As time went on and I knew I was going to be using 3 110v Pumps I had to work into the setup a way to control those pumps. So the design changed to something like this:

I designed it to use 1 drive bay to control both PSU's and the pumps.    So when you plug in 110V its originally NEVER touching the first PSU, it goes right past it down to the switch panel where its distributed. As we go through this part of the DH3 write up I will go into detail those switches and how its run.   The 12v layout is pretty simple. The Pelt control uses big 18 - 16 Gauge wire to handle the huge pull the pelts are going to have. The Switches are made to handle 20Amp at 12v so I am not worried about them.  As with the Cooling system I did a number of drafts in Photoshop to design the front bay panels.
