DKG-379 DC Genset Controller



The DKG-379 is an advanced DC genset controller for both variable and fixed speed systems. It is presented in 3 different versions, as ANALOG DRIVE, POWER DRIVE and CANBUS DRIVE.

The controller has a precision PID loop providing exact matching of the optimal charging characteristics, as well as overvoltage, overcurrent, overspeed, overheat protections.

The POWER DRIVE version provides a 7 Amp-DC output, interfacing directly to the engine actuator or alternator excitation winding without the need for a governor controller or AVR.

The CANBUS DRIVE version connects to ECU driven electronic engines providing engine control, protection and instrumentation without extra senders. ECU alarms are displayed in text.

All versions offer a 0-10V analog output for speed or voltage control.

The fixed speed operation stops the genset precisely when batteries are fully charged, providing fuel economy and maintenance cost reductions.

The unit has precision, fully isolated measuring inputs for the battery bank voltage and the charge current. It supports both “positive to ground” and “negative to ground” installations. The current is measured through a DC current shunt placed in positive or negative output of the genset.
