Integrating Your Power System

 

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.

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.

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.

Models Description
PLTO Open Transition Transfer with Programmed Transition Mode
PLTH 100 millisecond Closed Transition Transfer
PLTS Soft Loading Closed Transition Transfer
PLTE Extended Paralleling/Peak Shaving
