Notes
1) Reference conditions for engine performance according
to ISO 3046-1.
2) See rated capacity reduction diagrams or refer to the factory
for other conditions.
3) Under reference conditions, except for otherwise established.
At 50Hz only at 400V voltage.
4) Rated capacity definition (ISO 8528-1).
STBy: Limited Time Power is the maximum electric power
that a set of generators is able to supply (with variable
load) in case of a current failure (of up to 500 hours per
year, out of which, maximum 300 hours under continuous
running). Overload on these values is not allowed.
The alternator has a classification for continuous peaks
(as defined in ISO 8528-3)at 25ºC.
PRP : Primary Energy is the maximum available power
during a power variable sequence, that can run during
an unlimited number of hours per year, between stated
maintenance intervals and in the statedenvironmental
conditions. It is allowed 10% overload during 1 hour in
12 hours.The allowable average power during a 24-h
period shall not exceed the 100% stated load factor.
COP : The Estimate Continuous Power is the rated
power an engine is able to supply at constant load
for an unlimited number of hours per year, observing at
regular intervals, as per standard ISO 8528-1.
5) Specific mass of the fuel used.0.85 kg/l
(a) Thermal release is higher at 25ºC
