Genset performance classes
Genset performance classes are defined in ISO8528. In addition to the basic machine and manufacturer data, to comply with the above standard each Genset must have a rating plate that lists both the electrical and mechanical quantities, as well as the ambient reference parameters.
Power ratings
The type of use for which a generator set is applicable is determined by the reference power ratings. The rating must be defined on the nameplate affixed to the Genset. The power ratings are themselves governed by ISO8528-1.
COP: Continuous Operation Power
This is the maximum power a Genset can supply during continuous service, with a constant load for an unlimited number of operating hours, in the ambient conditions determined by the manufacturer and observing the maintenance intervals established by the manufacturer.A Silent & Open Frame generator which has a Stamford Alternator with a power range from 30 - 1000 <VA.
