POwer Control Systems

As with all digital systems, any requirement for diesel generator control can be met with the implementation of an appropriate control system. The control module is a full digital controller based on a microprocessor. It include generator controls, synchronization, load controls, sequential controls on generator set, electric parameter detection, protection, communication and display functions.

Power Command Control

With Cummins Power Generation you get a superior fully integrated digital power system – systems that are designed, built, tested and serviced by one manufacturer. As the only single-source manufacturer of engines, alternators, digital controls, transfer switches and digital paralleling systems, Cummins Power Generation leads the way in the seamless integration of power system technology.


It’s a proven systems approach that provides you with a superior power system and the easiest installation, along with low operating and maintenance costs. Generator paralleling controls Paralleling is an integrated function of our microprocessor-based Genset control, Power Command®. In addition to monitoring, protection, governing and voltage regulation functions, this single control provides paralleling control functions, including synchronizing, load sharing and paralleling protection. Power Command controls even provide utility (mains) paralleling functions such as import /export control and var/power factor control. Power Command controls were the first fully integrated paralleling control systems. Now with more than 10 years of experience and unmatched reliability.

Transfer Switches

Our transfer switches combine reliability and flexibility in a small, economical package for transferring loads between a utility and a generator set, or between two generators. The microprocessor control monitors utility and emergency standby generator power. When utility power fails or is unsatisfactory, the control starts the generator, then transfers the load from the utility to the generator. When stable utility power returns, the switch automatically transfers the load back to the utility.


For genset-to-genset applications, the genset that is connected to the utility side of the control is the lead genset. If the lead genset goes down or is taken offline, the transfer switch starts the second genset and transfers the load. The control can be programmed to alternate between the two gensets at a set interval up to 300 hours.
