5-5-4 DC Source Selector
This circuitry selects the source of the power. When the AC DC converter input into the system is higher
than 18V, the system will be powered by the AC DC converter. Otherwise, the selector will look for an
alternative power source (the battery), expecting to receive between 16 and 12V DC.
