Ratings Definitions

Prime Power – Model SW225P1

These ratings are applicable for supplying continuous electrical

power (at variable load) in lieu of commercially purchased power.

There is no limitation to the annual hours of operation and this

model can supply 10% overload power for 1 hour in 12 hours.

Standby Power – Model SW250E1

These ratings are applicable for supplying continuous electrical

power (at variable load) in the event of a utility power failure.

No overload is permitted on these ratings. The alternator on this

model is peak continuous rated (as defined in ISO8528-3).
