This
Electronic Test System (ETS) is used to test the Aircraft
Engine Generator System. The ETS monitors all input and
output power and displays AC/DC current input and output
up to 150-AMPs, it monitors feedback signals and output
signals form aircraft engine and displays all signals
on (29) digital meters on the front panel. It also provides
power to the aircraft main external power connector.
This
AC Test Console is manually operated and provides the
aircraft with the signal and 115-VAC, 3-Phase, 150-AMP,
400Hz power normally supplied by the aircraft engine generators
(3 generators, APU, and ADG).
