Cummins unveils paralleling genset controls

Thu, 11/15/2012 - 17:36 -- Ruth Williams

2-58aCummins Power Generation has introduced a new system-level control for parallel operation of multiple generator sets, the DMC 1500.

The DMC 1500 paralleling system combines Cummins Power Generation’s PowerCommand microprocessor-based control technology with a new icon-based graphical user interface designed to maximise user-friendliness. The system consists of a PowerCommand system-level digital master control integrated with custom-engineered switchgear. The DMC 1500 communicates directly with PowerCommand genset and transfer switch controls. 

Cummins’ DMC 1500 paralleling systems are offered for low or medium voltage applications. Typical emergency power applications include water treatment plants and office buildings. DMC 1500 systems can also be used for prime power at remote locations, such as mining facilities, where utility power is unavailable or unreliable.

With the DMC 1500 system, power transitions can be open or closed, in either fast (100 ms) or gradual ramping mode. The system includes utility paralleling functions for peak-shaving, base-loading and load add/load shed sequence control. The standard DMC 1500 accommodates four generators and can be expanded for up to eight generators.

A 15-inch touch-screen is used to control and monitor all functions, including system configuration and diagnostics. The intuitive graphic interface uses icons and menu bars for maximum usability and ease of navigation. Every screen includes a Help icon which, when pressed, brings up step-by-step instructions specific to the operation being performed.

A trained technician can perform all setup and service functions, including diagnostics, software upgrades and hardware upgrades. The standardised hardware layout, wiring harnesses and jack/plug connections simplify any required hardware servicing. 

The DMC 1500 Paralleling System is truly a global product, with multiple manufacturing locations to serve customer needs worldwide. The touchscreen user interface is available in seven languages. DMC 1500 system can be ordered with either UL/CSA or IEC/CE certification, and seismic certification.
