running). No overload is permitted on these ratings. The alternator is peak continuous rated (as defined in ISO 8528-3) at
25°C.
• PRP: Prime Power is the maximum power available during a variable power sequence, which may be run for an unlim-
ited number of hours per year, between stated maintenance intervals and under the stated ambient conditions. A 10%
