OPERATING DATA
STANDBY 45 kW
RATING: All single phase units are rated at 1.0 power factor. STANDBY RATING: Standby ratings apply to installations served by a reliable utility
source. The standby rating is applicable to varying loads for the duration of a power outage. There is no overload capability for this rating. Ratings
are in accordance with ISO-3046-1. Design and specifications are subject to change without notice. Maximum wattage and current are subject to
and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc.
