The deviation output is capable of driving up to three 1000
Ω
loads with
±
150 mVDC
±
5% for full-scale
deflection. The drive circuit provides for more than full-scale deflection with a maximum course
deviation output voltage of ±300 mVDC

The output supplies not less than 500 mA on a 28 volt system with the output voltage not less than
(AIRCRAFT POWER –2.0 VDC) when the flag is to be OUT OF VIEW. The output voltage with
respect to ground is less than 0.25 VDC when the flag is to be IN VIEW.
