2.2.1 - Options
- Protection against harsh environmentsh.
- Air input filter, air output labyrinth cowling.
Alternators fitted with air inlet filters should be derated by 5%
(power).
To prevent excessive temperature rise caused by clogged
filters, it is advisable to fit the stator winding with thermal
sensors (PTC or PT100).
