DESCRIPTION
Supplied with 24V to 28V DC, the rotary inverter produces 115V 400Hz 3-phase AC.
Lightings all used a Type 100A inverter, but as beggars can't be choosers, I am using a Type 100B inverter as it's what was available. The main difference is the connectors used, and shape of its enclosure, functionally they are very similar.
Type 100A inverter installed in T5 Lightning XS458, 2012.
While 28V DC is mostly harmless, the 115V AC output could cause an electric shock if great care is not taken.
SIMULATION
Several of the indicators used in the Lightning need a 400Hz AC power supply to operate their internal motors and synchros. The Lightning's Type 100A inverter is normally only used when the aircraft is on the ground, and only has a DC supply (internal battery or trolley acc.) as when the engines are running, AC is supplied form the main alternator. Alternatively when on the ground, a ground generator suchas a Houchin can also supply the AC power.
The use of an inverter in this simulator project is to supply the instruments in all scenarions. Being a simulator it has no engines or internal alternator, nor ground generator, so the one inverter supply will have to be used to mimic all three of the real scenarios.
