_______________________________________________________________________
1. Electrical Power Supply
_______________________
A. 28VDC Power Supply
(Ref. Fig. 001)
The FAC1 is supplied with 28VDC:
-
From the 28VDC ESS BUS 4PP through the 28VDC ESS BUS 801PP via 10A
circuit breaker 5CC1.
The FAC2 is supplied with 28VDC:
-
From the 28VDC BUS 2 2PP through the 28VDC BUS 2 206PP via 10A circuit
breaker 5CC2.
The 28VDC power supply generates:
-All the voltages associated with internal computation (+ 5VDC, + 15VDC and - 15VDC)
-The logic processing voltages (discretes, relays, etc.).
All these voltages derived from the 28V power are monitored by the FAC in
the command and monitoring channels.
B. 26V/400 Hz Power Supply (Ref. Fig. 002) The Rotary Variable Differential Transformers (RVDT) and the Linear Variable Differential Transformers (LVDT) associated with the FAC1 are supplied with 26V/400 Hz: 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM AUTO FLIGHT 自动飞行2(42)
