Rectifier Shelves
Rectifier shelves are equipped in either two shelf (500A system) or four shelf (1000A
system) arrangements. DC output from each rectifier is bused up the back to the
distribution and protected by clear lexan covers. Individual AC feeds from terminal
blocks in the ac box route down the ac duct to a connector on each shelf. Serial
communication cables daisy-chain from QS845A interface boards on the left side of each
shelf and up to the controller.
The system is designed to allow field upgrades from two shelf to four shelf systems. This
can be safely accomplished on working systems because the new shelves are first
installed and then bus and cable links added.
