Air Excess (lambda)
fuel efficiency and low emissions for high-hour peaking baseload and CHP
applications. Using a lean mixture of fuel and air, combustion temperatures
are significantly reduced, which minimizes the production of nitrogen oxides.
The result is high power output with maximum thermal efficiency and minimal
emissions. Already proven in over 500,000 hours of continuous duty operation
around the world, these generators meet most federal, state, and local emissions
requirements. SCR after treatment options reduce NOx levels (as low as 0.15
grams/BHP-hr or less) to the most stringent air quality standards. Capable of
running on variable quality gas — from pipe-line natural gas to field gas or bio-gas
with a methane number over 45, Cummins gas reciprocating engine technology
and standard PowerCommand controls provide maximum operational
flexibility for power generation applications.

DIGITAL PARALLELING AND POWER TRANSFER EQUIPMENT
Paralleling is an integrated function of our microprocessor based
genset control, PowerCommand. In addition to monitoring, protection,
governing, and voltage regulation functions, this single control provides
paralleling control functions, including synchronizing, load sharing,
and paralleling protection. PowerCommand controls even provide
utility (mains) paralleling functions such as import/export control
and var/power factor control. The same microprocessor-based control
technology is also found on our full line of transfer switches;
optimizing performance and simplifying operation and
service. Only with Cummins Power Generation can you get
a pre-integrated digital power system—systems that are designed,
built, tested and serviced by one manufacturer.
Digital MasterControl
The PowerCommand Model 200 and 300 Digital MasterControl, with its
unique industrial PC-based touchscreen operator interface and software-based
design, is a perfect complement to the PowerCommand generator set control for
applications that demand maximum ease of use and extensive control capabilities.
Major features include:
• Internet/Intranet capable for remote monitoring and alarm dialout
• Broad range of master control products to suit any application
• Isolated and infinite bus (utility mains paralleling) designs
• Easily integrates into other building control systems
• Suitable for applications up to 15,000 VAC, ANSIC 37.2, UL-1670 listed
• Power sections available using either stationary or drawout breakers, in
UL-891, UL-1558 CSA or IEC type medium voltage designs, UL-1670 listed

Digital Paralleling Transfer Equipment
and Closed Transition Transfer Switches
Closed transition transfer switches from 125 to 800 amps
operate either open or closed hard transition with enhanced
specific breaker ratings and 3 cycle ratings. Closed transition
includes sync check or optional active sync for short duration
paralleled source operation (50 –70 msec). For installations
rated from 800 – 3,000 amps, our digital paralleling load
transfer (PLT) equipment, specifically designed for closed
transition transfer, transfers power between a generator set
and utility service without interrupting power to critical
loads. Service entrance rating, ground fault protection, and
utility protective relaying are available. UL-891, UL-1008 listed.

Open Transition Transfer Switches
Our open transition transfer switches incorporate a range of controls for
utility-to-utility, utility-to-genset or genset-to-genset applications. They employ
many standard and optional features, including a front panel digital display, bar
graph metering, programmed transition, phase check, and optional simultaneously
switched neutral. Major features include:
• UL 1008 listed withstand and closing ratings up to 200kA
• High visibility LED-indicating lamps provide
at-a-glance source and ATS status for quick summary
of system conditions
• Convenient front panel digital display provides easy
access to review power and load conditions, make
adjustments, review events, and check network status
• Designed to be configurable through the front panel

Bypass Isolation Transfer Switches
Our bypass isolation transfer switch combines an open transition transfer switch,
a two-source manual bypass switch, a closed door drawout isolation mechanism,
and microprocessor-based controls. The switch allows maintenance, service and
testing of the ATS without disrupting power to critical loads. For environments
with critical power requirements, such as healthcare and data center facilities, the
bypass isolation switch will combine safe reliable service with simple operation.
Major features include:
• Non-load break bypass operation maintains
service to critical loads when the ATS is drawn
out of service
• External manual operation capability for the ATS
• Dead source interlocks prevent the operator
from connecting loads to a failed utility or
generator source
• Full mechanical interlock system prevents
accidental interconnection of the power sources

Our non-automatic transfer switches are operated
electrically through a front panel mounted control
switch. They are available from 40 to 3,000 amps.
