Description
Features
The Cummins Power Generation DG-series commercial
generator set is a fully integrated power generation system
providing optimum performance, reliability, and versatility for
stationary standby or prime power applications.
UL Listed Generator Set - The complete generator set
assembly is available Listed to UL 2200.
A primary feature of the DG GenSet is strong motor-starting
capability and fast recovery from transient load changes. The
torque-matched system includes a heavy-duty Cummins 4cycle diesel engine, an AC alternator with high motor-starting
kVA capacity, and an electronic voltage regulator with three
phase sensing for precise regulation under steady-state or
transient loads. The DG GenSet accepts 100% of the
nameplate standby rating in one step, in compliance with
NFPA 110 Level 1 requirements.
Cummins Heavy-Duty Engine - Rugged 4-cycle industrial
diesel engine delivers reliable power, low emissions, and
fast response to load changes.
The standard PowerCommand® digital electronic control is an
integrated system that combines engine and alternator
controls for high reliability and optimum GenSet performance.
Optional weather-protective enclosures and coolant heaters
shield the generator set from extreme operating conditions.
Environmental concerns are addressed by low exhaust
emission engines, sound-attenuated enclosures, exhaust
silencers, and dual-wall fuel tanks. A wide range of options,
accessories, and services are available, allowing configuration
to your specific power generation needs.
Every production unit is factory tested at rated load and power
factor. This testing includes demonstration of rated power and
single-step rated load pickup. Cummins Power Generation
manufacturing facilities are registered to ISO9001 quality
standards, emphasizing our commitment to high quality in the
design, manufacture, and support of our products. The
generator set is CSA certified and is available as UL2200
Listed. The PowerCommand control is UL508 Listed.

Alternator
Several alternators are available for application flexibility based on the required motor-starting kVA and other requirements.
Larger alternator sizes have lower temperature rise for longer life of the alternator insulation system. In addition, larger
alternator sizes can provide a cost-effective use of engine power in across-the-line motor-starting applications and can be
used to minimize voltage waveform distortion caused by non-linear loads.
Single-bearing alternators couple directly to the engine flywheel with flexible discs for drivetrain reliability and durability. No
gear reducers or speed changers are used. Two-thirds pitch windings eliminate third-order harmonic content of the AC
voltage waveform and provide the standardization desired for paralleling of generator sets. The standard excitation system is
a self (shunt) excited system with the voltage regulator powered directly from the generator set output.
Alternator Application Notes
Separately Excited Permanent Magnet Generator (PMG) System - This option uses an integral PMG to supply power to
the voltage regulator. A PMG system generally has better motor-starting performance, lower voltage dip upon load
application, and better immunity from problems with harmonics in the main alternator output induced by non-linear loads. This
option is recommended for use in applications that have large transient loads, sensitive electronic loads (especially UPS
applications), harmonic content, or that require sustained short-circuit current (sustained 3-phase short circuit current at
approximately 3 times rated for 10 seconds).
Alternator Sizes - On any given model, various alternator sizes are available to meet individual application needs. Alternator
sizes are differentiated by maximum winding temperature rise, at the generator set standby or prime rating, when operated in
o
o
o
a 40 C ambient environment. Available temperature rises range from 80 C to 150 C. Not all temperature rise selections are
available on all models. Lower temperature rise is accomplished using larger alternators at lower current density. Lower
temperature rise alternators have higher motor-starting kVA, lower voltage dip upon load application, and they are generally
recommended to limit voltage distortion and heating due to harmonics induced by non-linear loads.
Alternator Space Heater - is recommended to inhibit condensation.
