A320 SDACs 26VAC supply
Dear colleagues,
The data even in the official data package is so scarce that I have to appeal for your help. Unfortunately, I have no access to the real aircraft.
There are 5 CBs that protect the 26VAC lines to the SDACs. They are the following:
5WV (location is 49VU-F02) feeds SDAC1 from the 431XP bus bar of the AC ESS BUS.
6WV (location is 49VU-F03) feeds SDAC2 from the 431XP bus bar of the AC ESS BUS.
7WV (location is 121VU-Q03) feeds SDAC1 from the 231XP bus bar of the AC 2 BUS.
8WV (location is 121VU-Q02) feeds SDAC2 from the 231XP bus bar of the AC 2 BUS.
10WV (location is 121VU-Q05) feeds SDAC2 from the 131XP bus bar of the AC 1 BUS.
They all are labeled as SDAC 1(2) 26VAC sync. I understand that this input is used anywhere where angle measurement is required, specifically flaps, slats, and other flight controls. But which one is used for which? What will be the immediate effect on indication, if every of these CBs is tripped? If you could make a reference to some Airbus document which is available, it would be just brilliant.
