DKG-379 User Manual Rev_02
DESCRIPTION
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.
The genset starting is based on the precisely measured DC
battery bank voltage. Once started, the controller will perform
an optimal battery charging cycle and will stop the genset
when batteries are fully charged. The optimal charge algorithm
allows maximum battery life and minimal engine run time and
fuel consumption.
During the charge cycle, the unit controls the engine rpm (or
excitation) in order to apply the exact required DC voltage and
current to batteries. The rpm control over CANBUS-J1939 is
available for electronic engines.
The unit offers a PT100 type, battery temperature sensor
input. If used, the temperature protection will allow longer
battery life in hot environment and faster charge in cold
conditions.
