utility power failure (for up to 500 hours per year of which a maximum of 300 hours is continuous 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 unlimited number of hours per
year, between stated maintenance intervals and under the stated ambient conditions. A 10% overload is permitted for 1 hour in 12 hours. The
permissible average power output during a 24h period shall not exceed the stated load factor of 70%.
