DKG307 Genset Controller – Robust AMF Control for Reliable Diesel Generator Operation

1. Integrated AMF Functionality for Unattended Operation
The DKG307 Genset Controller is a dedicated Automatic Mains Failure (AMF) unit designed to deliver seamless backup power management. It continuously monitors grid voltage (up to 300Vac, 0-100Hz) and frequency, automatically initiating generator startup within seconds of a mains failure. When grid power is restored, the controller executes a smooth load retransfer and initiates a controlled generator shutdown after a programmable cool-down period, eliminating the need for manual intervention. This makes it ideal for unattended remote sites, critical infrastructure, and standby power systems where reliability is paramount.

2. Multi-Parameter Digital Monitoring & Alarm System
At its core, the DKG307 features a bright 3-digit LED display that provides real-time visibility into key operating parameters:
Electrical Parameters: Generator voltage (V~), current (A~), DC battery voltage (Vdc), frequency (Hz), and power (kW).
Engine Parameters: Oil pressure, coolant temperature, fuel level, and engine speed (via MPU input).
Comprehensive Alarm Indicators: A dedicated alarm panel displays 14 distinct fault conditions, including low oil pressure, high temperature, speed faults, start/stop failures, low fuel, overload, battery issues, and service requests. Each alarm is clearly labeled with an icon, enabling operators to quickly identify and resolve issues.

3. Intuitive Front-Panel Control & Configuration
The DKG307 simplifies operation with a user-friendly front-panel interface:
Function Buttons: Dedicated keys for MENU navigation, TEST mode, RUN (manual start), AUTO (AMF mode), and STOP (emergency shutdown) provide direct access to core functions.
Menu Navigation: The MENU button allows for easy configuration of critical parameters such as start/stop delays, alarm thresholds, and protection setpoints, all accessible without the need for external software.
Status Visualization: A top-panel schematic illustrates the power flow between the mains, generator, and load, providing at-a-glance system status.


4. Robust Industrial Design & Connectivity
Built to withstand harsh generator environments, the DKG307 offers:
Wide Voltage Input: Operates on 9-33Vdc (200mA max), ensuring compatibility with a range of battery systems and generator setups.
Secure Terminal Blocks: Rear-mounted green terminal blocks (labeled 1-34) provide stable, vibration-resistant connections for sensors, actuators, batteries, and auxiliary outputs, simplifying installation and reducing wiring errors.
RS232 Communication: A built-in RS232 serial port enables integration with remote monitoring and control systems, allowing for scalable system design and remote diagnostics.
Relay Extension: Supports relay expansion for additional control outputs, making it suitable for complex generator applications.

5. CE Certified Quality Assurance
The DKG307 is manufactured to meet strict international standards, with CE certification ensuring compliance with electrical safety and EMC directives. Rigorous pre-shipment testing, including functional validation and environmental simulation, guarantees consistent, failure-free performance in demanding applications.

1. Standby Power for Critical Infrastructure
The DKG307 is the backbone of backup power systems for hospitals, data centers, and industrial plants, ensuring zero downtime during grid outages and protecting sensitive equipment and life-saving services.

2. Remote & Off-Grid Power Systems
Ideal for telecommunications towers, remote mining sites, and agricultural installations, the DKG307 operates reliably in harsh environments with minimal maintenance. Its AMF functionality and remote monitoring capabilities reduce operational costs for unattended locations.



3. Commercial & Industrial Standby Generators
Widely used in commercial buildings, manufacturing facilities, and retail stores, the controller provides reliable backup power with automatic operation, even when facilities are unoccupied. The LED display and alarm system simplify maintenance, ensuring generators are always ready to perform when needed.

4. Generator Retrofit Projects
The DKG307 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 intuitive interface simplify retrofitting, making it a cost-effective upgrade for older generator fleets.

5. OEM Integration for Generator Manufacturers
Leading generator OEMs integrate the DKG307 into their products to meet global safety and performance standards. Its robust design, comprehensive features, and international certifications enhance product competitiveness in global markets, providing customers with a reliable, future-proof control solution.

The DKG307 Genset Controller is a robust, reliable, and user-friendly control solution for diesel generators, combining integrated AMF functionality, comprehensive monitoring, and intuitive operation.
