Each rack (power shelf) is 1U high with backplane and designed for up to five front-end models in parallel or in n+1 operation.

Each power shelf has:



Output terminals with two M4-screws on each power tab.



Two fast-on contacts for system earthing.



support functions.



Provides a start-up synchronization circuit and EMV filters.
