Overview

Cummins generator sets are fully integrated power generation systems providing optimum performance an reliability for stationary Standby applications.

Heavy Duty Engine - The rugged 4-cycle industrial Cummins QSB7 diesel engine delivers reliable power, low emissions and fast response to load changes.

Alternator - Several alternator sizes offer selectable motor starting capability with low reactance 2/3 pitch windings, low waveform distortion with non-linear loads and fault clearing short-circuit capability.

Control System - The PowerCommand® 1.1 electronic control is standard equipment and provides total generator set system integration, monitoring and control.
