Control system 

The PowerCommand control system is an integrated microprocessor based generator set control system providing voltage regulation, engine protection, alternator protection, operator interface and isochronous governing. 

AmpSentry – Includes integral AmpSentry protection, which provides a full range of alternator protection functions that are matched to the alternator provided.

Power management – Control function provides battery monitoring and testing features and smart starting control system. 

Advanced control methodology – Three phase sensing, full wave rectified voltage regulation, with a PWM output for stable operation with all load types.

Communications interface – Control comes standard with PCCNet and Modbus interface. 

Regulation compliant – Prototype tested: UL, CSA and CE compliant. 

Service - InPower PC-based service tool available for detailed diagnostics, setup, data logging and fault simulation. 

Reliable design – The control system is designed for reliable operation in harsh environment. 

Multi-language support

Operator panel features 

Operator panel features – The operator panel, in addition to the alternator, displays the Utility/AC Bus data.
