What is the power source for the Digital Electronic Control?

Explanation:
Digital Electronic Control runs off the aircraft’s electrical system, not from the battery or other special sources. Its main power comes from the AC airframe power provided by the engine-driven generators (the alternator). The battery serves primarily for starting and certain backup needs, and ground power units can supply power on the ground but are not the normal flight source. Solar power isn’t used in this system. So the best answer is that the DEC is powered by the alternator or AC airframe power.
