STATIC INVERTER
A static inverter transforms DC power from Battery 1 into one KVA of single-phase 115-volt
400-hertz AC power, which is then supplied to part of the AC essential bus. When the
aircraft speed is above 50 knots, the inverter is automatically activated, if nothing but the
batteries are supplying electrical power to the aircraft, regardless of the BAT 1 and BAT 2
pushbutton positions.
When the aircraft speed is below 50 knots, the inverter is activated, if nothing but the
batteries are supplying electrical power to the aircraft, and the BAT 1 and BAT 2
pushbuttons are both on at auto.
DC GENERATION
TRANSFORMER RECTIFIERS (TRs)
Two main transformer rectifiers, TR 1 and TR 2, supply the aircraft's electrical system, with
up to 200 amperes of DC current.
A third (identical) transformer rectifier, the ESS TR, can power the essential DC circuit from
the emergency generator, if the engine and APU generators all fail, or if TR 1 or TR 2 fails.
Each TR controls its contactor by internal logic.
BATTERIES
Two main batteries, each with a normal capacity of 23 ampere-hours, are permanently
connected to the two hot buses.
Each battery has an associated Battery Charge Limiter (BCL).
The BCL monitors battery charging and controls its battery contactor.
CIRCUIT BREAKERS (C/Bs)
The aircraft has two types of C/Bs :
- Monitored (green) : When out for more than one minute, the C/B TRIPPED warning is
triggered on the ECAM.
- Non-monitored (black).
The Wing Tip Brakes (WTB) C/Bs have red caps on them to prevent them from being reset.
The C/B TRIPPED warning on the ECAM indicates the location of the affected C/B. The
following panels are monitored : OVHD PNL, L(R) ELEC BAY, REAR PNL J-M or N-R or S-V
or W-Z
Note : The C/B TRIPPED, warning may be cleared from the ECAM. In this case, if a second
C/B is tripped on the same panel, the corresponding C/B TRIPPED warning will not
be triggered.
