DKG-300 Genset Controller – Advanced Automatic Control for Modern Diesel Generators

1. Intuitive LCD Interface & Simplified Operation
The DKG-300 Genset Controller features a clear monochrome LCD display paired with dedicated front-panel buttons, designed for intuitive operation and real-time status monitoring:
RUN (Green Button): Manually initiates generator startup, with built-in pre-heat and cranking protection to prevent starter motor damage.
AUTO (White Button): Enables automatic mains failure (AMF) mode, where the controller monitors grid voltage/frequency and starts the generator automatically during outages, then transfers load back to the grid once power is restored.
STOP (Red Button): Initiates a controlled shutdown (with cool-down delay) or emergency stop for critical faults.
TEST Button: Allows for routine system testing to verify generator and controller functionality.
Status Indicators: Visual icons show mains status, generator running, fault conditions (alarm/warning), and service requests at a glance.
This user-friendly interface reduces training time for technicians and minimizes operational errors, even in high-stress environments.

2. Comprehensive Multi-Parameter Monitoring & Protection
At its core, the DKG-300 provides robust protection for both the engine and electrical system, monitoring critical parameters in real time:
Engine Protection: Monitors oil pressure, coolant temperature, RPM, fuel level, and starter health, triggering alarms or shutdowns for under-pressure, over-temperature, overspeed, or low fuel conditions.
Electrical Protection: Tracks generator voltage (up to 300Vac, 50/60Hz), current, frequency, and phase balance, with built-in over/under voltage, overcurrent, short-circuit, and reverse power protection.
Battery Monitoring: Monitors battery voltage (8-36Vdc, 500mA max) to prevent deep discharge and ensure reliable starting, even in cold conditions.
The controller also includes a fault history log, storing up to 50 recent events for troubleshooting, reducing maintenance time and costs.

3. Flexible Configuration & USB Programming
A key advantage of the DKG-300 is its flexible configuration options, supported by a rear-mounted USB port for easy programming:
Customizable Parameters: Adjust start/stop delays, load transfer thresholds, protection setpoints, and idle speed via USB-connected software, tailoring the controller to specific generator models and site requirements.
Wide Compatibility: Supports generators from 10kVA to 1500kVA, and integrates seamlessly with all major engine brands (Cummins, Perkins, Volvo, etc.) and alternators.
Expandable Connectivity: Optional CAN bus and extension plug-in modules enable integration with SCADA, building management systems (BMS), and remote monitoring platforms, allowing for scalable system design.

4. Robust Industrial Design for Harsh Environments
The DKG-300 is built to withstand the extreme conditions of industrial and marine generator rooms:
Heavy-Duty Enclosure: A rugged black plastic casing provides dust, moisture, and impact resistance, with an operating temperature range of -10°C to +60°C.
Potted Electronics: Internal components are sealed with epoxy resin, protecting against oil, fuel, and coolant contamination, ensuring reliability in corrosive environments.
Secure Terminal Blocks: Rear-mounted green terminal blocks (labeled 1–72) provide stable, vibration-resistant connections for sensors, actuators, batteries, and auxiliary outputs, simplifying installation and reducing wiring errors.

5. CE & EAC Certification for Global Compliance
Every DKG-300 controller is manufactured in an ISO 9001 certified facility and meets CE and EAC (Eurasian Conformity) electrical safety standards, ensuring compliance with international regulations. Rigorous quality control includes component inspection, functional testing, and environmental simulation, guaranteeing consistent, failure-free performance in critical applications.

1. Critical Facility Backup Power Systems
The DKG-300 is the ideal choice for backup power systems in data centers, hospitals, financial institutions, and industrial plants. Its automatic AMF mode ensures seamless power continuity during grid outages, protecting sensitive equipment and life-saving services, while comprehensive protection features prevent costly generator damage.

2. Commercial & Industrial Standby Generators
Widely used in commercial buildings, manufacturing facilities, and retail stores, the DKG-300 provides reliable backup power with automatic operation, even when facilities are unoccupied. The LCD display and fault log simplify maintenance, ensuring generators are always ready to perform when needed.


3. Remote & Off-Grid Power Solutions
Ideal for telecommunications towers, remote mining sites, and agricultural installations, the DKG-300 operates reliably in harsh environments with minimal maintenance. USB programming and remote monitoring capabilities reduce the need for on-site visits, lowering operational costs for unattended locations.

4. Generator Parallel Cabinet Systems
In parallel systems, the DKG-300 coordinates multiple generators to share loads evenly and start/stop based on demand, ensuring efficient and redundant power delivery for large-scale industrial applications. Its flexible configuration allows seamless integration with switchgear and load transfer systems.


5. Retrofit of Legacy Generator Controllers
The DKG-300 is a direct drop-in replacement for outdated manual controllers, upgrading existing generator systems with advanced automation and protection without costly overhauls. Its standard terminal block layout and USB programming simplify retrofitting, making it a cost-effective upgrade for older generator fleets.

6. OEM Integration for Generator Manufacturers
Manufacturers of modern diesel generators integrate the DKG-300 into their products to meet global safety and performance standards. Its compact design, comprehensive features, and international certifications enhance product competitiveness in global markets, providing customers with a reliable, future-proof control solution.

The DKG-300 Genset Controller sets a new standard for intelligent generator control, combining an intuitive interface, comprehensive protection, flexible configuration, and robust industrial design. Whether used in critical backup power systems, remote off-grid applications, or modern parallel generator setups, the DKG-300 delivers reliable, uninterrupted power when it matters most. Backed by global certifications and a 1-year warranty, it is a trusted choice for operators and manufacturers worldwide.
