DATAKOM DKG-379-POWER-MPU Advanced DC generator controller, 7A actuator output

* All prices are retail and VAT exclusive

The DATAKOM 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.
The controller is able to read the engine speed from charge alternator or MPU pulses.
The unit supports both single genset standby and dual genset mutual standby operations.
The unit is able to initiate modem calls and send SMS messages in fault conditions through external modem.
The unit provides a comprehensive set of programmable parameters. All programs may be modified via front panel pushbuttons.
The unit provides Modbus protocol, which is available through both RS-232 and modem connections.
