PC POWER SYSTEM
The PC Power system is designed to supply aircraft seats with
110V/60Hz AC-power for Personal Electronic Devices (PED) such as
laptop computers and other passenger equipment.
A control switch in the In-flight Entertainment Panel (IFE), installed in
the Cockpit Overhead Panel, controls the PC Power System.
The Master Control Unit (MCU) controls the power available to the AC
Outlet Units in the seat armrest. The MCU has power programming
capability, which monitors the total electrical current in use at the
Outlet Units and, if necessary, disables or enables the available power
outlets.
If any cabin decompression occurs during the flight, the MCU is
deactivated by a ground signal from the pressurization system.
Each outlet incorporates a LED, that is visible to the passenger and
indicates that AC power is available. The green color indicates the
power supply, the yellow color indicates power not available at the
moment, and the red color indicates that AC outlet unit out of service.
A blue color LED on the aisle seats indicates if the In-Seat Power
Converter is providing power.
NOTE: The PC Power System may be turned off during take-off and
landing conditions or when operating below 10000 ft.
