Cummins Power Generation on-site power
generation systems are the result of integrated design and
manufacturing intended to satisfy our customer's requirements
for reliability, power quality, rated performance, and
efficient operation. For either standby or prime power, we
produce a full line of diesel and spark-ignited generator
sets, transfer switches, paralleling switchgear, sound
attenuated housings, and installation accessories.
Product Line
PowerCommand®, is the power
system that does it all. With pre-integrated gensets, transfer
switches, paralleling equipment, and controls, we can reduce
the complexities of system design and installation. Smart
microprocessing gives the system unprecedented power to
monitor itself. And interoperability provides the flexibility
of integrating standby power with a building automation
system. If you're looking for a breakthrough system with all
kinds of power, this is the one.

Spark-Ignited Generator Sets, 6
to 150 kW
Our spark-ignited generator sets, 6.0 to 150 kW,
are designed for applications that call for gaseous fuel
options as a result of fuel containment, economic and
emissions considerations, or compliance with local codes.
These generator sets have fuel systems for both natural gas
and propane, making them a convenient choice for a variety of
life-support and related applications, including small health
care facilities and retail businesses.

DC Generator
Sets 3.0kW to 5.5kW
Reliable Cummins DCathlon® generator sets are designed to keep remote
telecom and wireless sites running. They enhance system
reliability and reduce your battery plant, lowering battery
costs and cabinet space requirements while providing long-term
backup power.
DCathlon generator sets improve
reliability by connecting directly to the DC bus, bypassing
the rectifier and eliminating the need for a transfer
switch.
Monitor remotely without using
revenue-generating phone lines. And continuously monitor
your battery plant, simplifying maintenance. All
generator sets are tested to meet Telecordia/Bellcore
requirements, such as: GR-63, GR-487, GR-1089 and
UL2200.
More information is available in this
telecommunications case
study or through product spec sheets: 3.0kW,
4.5kW
or 5.5kW.
PowerCommand Automatic and Bypass Isolation
Transfer Switches
Cummins Power Generation transfer switches
maintain the critical link between the normal power source and
the power generation system. With over 100,000 installations
worldwide, we provide switches for everything from the
simplest applications requiring low amperage and basic
switching to more robust environments with critical power
requirements.

PowerCommand Digital
Paralleling Equipment  
With PowerCommand, paralleling can be an
integrated function of the genset control. In addition to all
monitoring, protection, governing, and voltage regulation,
PowerCommand provides all paralleling control functions,
including synchronizing, load sharing, and paralleling
protection plus utility (mains) paralleling functions such as
import/export control and var/power factor control. Digital
design and integration saves space and vastly improves power
system reliability and performance.
PowerCommand Digital
Paralleling Load Transfer Equipment
Specifically designed for use in the front end of
electrical power distribution systems, our digital paralleling
load transfer equipment, rated from 800 to 3000 amps,
transfers power between a generator set and utility service
without disturbing the operation of critical loads such as UPS
equipment. Service entrance rating, ground fault protection
and protective relaying are available.
