.
AC bus 1, 2, 3 and 4 (ACPC).
.
AC bus 1A, 2A, 3A, essential bus (CCBP).
A ram air turbine (RAT) deployable during flight, supplies 115.volt, 400.Hz, 3.phase AC power 9 KVA for emergency use (when all other AC sources have been lost) to supply AC power to the AC essential bus. Mounted on the RAT is a hydraulic pump which powers hydraulic system #3.
For other load devices requiring DC power, 115–volt AC power is converted to 28–volt DC power by four 150 Amp transformer-rectifier units (TRU). 28–volt DC power is distributed through the DC power center (DCPC) and the secondary power distribution assemblies (SPDA) on the following busses:
.
DC bus 1 and 2
.
DC essential bus
.
Battery bus
.
DC Emergency bus
The 25–ampere hour, 24–volt DC avionics battery provides power to the following:
.
Stored energy to selected electronic equipment during normal ground operations.
.
During flight in an emergency (loss of all generators) to the flight essential DC loads.
The 42 ampere hour, 25.2 volt DC APU battery provides power to the following:
.
Stored energy for starting the APU during both ground and flight operations.
.
During flight in an emergency (loss of all generators) to the flight essential DC loads.
The following busses are connected directly to the battery terminals:
.
Avionics battery direct bus
.
APU battery direct bus
Battery chargers and battery heaters, powered by the main AC buses, maintain the main and APU batteries in a charged and warm condition.
An Electrical Control Panel, located in the cockpit, provides control of all generators, external AC and DC power and battery master.
An Electrical Management System (EMS), located in the cockpit, controls and displays the status of circuit breaker, on the two control display units (CDU).
External AC power, supplied through the AC receptacle, situated at the aft left side of the airplane (on the fairing at the root of the wing trailing edge) provides power to:
.
AC bus 1, 2, 3 and 4.
.
AC 1A, 2A, 3A and essential bus.
External DC power, supplied through the DC receptacle, situated at the aft of the airplane (adjacent the aft service panel), provides power to the APU battery direct bus.
The APU can be started using external DC power.
The airplane batteries cannot be charged through external DC power.
