ROCK AB-R20SS/T
P.R.P. Prime Power-Continuous power at variable load:
nThe power that a genset can
nsupply in continuous service at a variable load for an unlimited number of hours per year while respecting the maintenance intervals established in the environmental conditions stated by the Manufacturer. according to ISO8528-1. The average power supplied over time and any applicable overload must be less than the percentages stated by the Manufacturer.
