pcc3100 Control System
PowerCommand™ 3100 - Generator Set Control
Description
The PowerCommand™ 3100 Control is a microprocessor-based generator set monitoring, and
control system. The control provides an operator interface to the genset, digital voltage regulation,
digital governing and generator set protective functions.
The PowerCommand™ 3100 generator set control is suitable for use on a wide range of generator
sets in non-paralleling and paralleling applications
The PowerCommand™ Control can be configured for any frequency, voltage and power connection
configuration from 120 to13,800 VAC for for 50Hz or 60Hz operation.
Power for the control is derived from the generator set starting batteries. The control functions over a
voltage range from 8VDC to 35VDC.
Major Features
Digital Governing and Voltage Regulation, including digital overcurrent fault regulation.
Digital Voltage Regulation with 3-phase sensing
AmpSentry™ Protection for true alternator overcurrent protection.
