POWER REQUIREMENTS
The ATR 720 C requires 13.75 volts for proper operation. Aircraft having electrical power plants
producing 27.5 volts, require the installation of a voltage converter. The PS 2814 Voltage Con-
verter, designed to convert 27.5 volts to 13.75 volts, may be conveniently remote mounted in the
aircraft.
