This rating incorporates a 10% overload capability, and conforms to ISO 8528 prime power. Average
10 38 load over a 24-hour period shall not exceed 67% of the prime rating, of which no more than 2 hours
are between 100% and 110% of the prime rating.
Constant speed engines are not certified for constant speed propulsion applications (i.e. variable
8 30 pitch proppeller, hybrid porpulsion system).
Possible applications: This rating is used for applications that require constant speed operation in
power generation or auxiliary applications such as generators and hydraulic pumps.
