Basler Electric DGC‑2020 Digital Genset Controller

The Basler Electric DGC‑2020 is a state‑of‑the‑art digital controller designed for managing diesel, gas, and dual‑fuel generator sets. It integrates engine start/stop logic, generator protection, load control, and communication functions into a single compact unit. The controller is suitable for standby, prime power, and parallel operation applications, providing advanced features that enhance reliability and ease of use.

Display and User Interface

The DGC‑2020 features a 4.3‑inch color TFT display with customizable screens showing real‑time parameters such as voltage, current, frequency, engine RPM, temperature, and fuel level. Five navigation buttons and a jog dial enable intuitive menu navigation. The display supports multiple languages and can be configured to show alarms, events, and graphical trends. The user interface is designed for quick access to settings and diagnostics.

Control and Protection

The controller provides automatic start/stop based on utility failure or remote commands, with programmable timers for crank, pre‑heat, and cooldown. It includes comprehensive protection: over/under voltage, over/under frequency, reverse power, overcurrent, and engine protection (low oil pressure, high coolant temperature, overspeed). All setpoints are adjustable via the front panel or PC software. The DGC‑2020 also supports automatic transfer switch (ATS) logic and load shedding.

Communication and Connectivity

Built‑in communication ports include RS‑232, RS‑485, and USB, supporting protocols such as Modbus RTU, Modbus TCP (with optional Ethernet), and CAN bus for engine interface (J1939). Remote monitoring and control are possible via optional GSM/GPRS or Wi‑Fi modules. The controller is compatible with Basler Electric’s AEM‑2020 analog expansion module for additional inputs/outputs.

Technical Specifications

Power supply: 8‑35 VDC (12/24 V battery system). Measuring inputs: 3‑phase voltage (up to 600 VAC), CT current (1/5 A). Accuracy: ±0.5% for voltage/current. Operating temperature: –20°C to +70°C. Enclosure: IP54 front panel, IP20 rear. Mounting: panel cutout 180 x 130 mm. Approvals: CE, UL pending.

Applications

The DGC‑2020 is used in diesel generator sets, gas generator sets, and cogeneration systems. It is ideal for data centers, hospitals, telecommunications, and offshore installations where reliable and intelligent generator control is essential. It can be used in single or multiple generator parallel systems with load sharing.

Installation and Configuration

Mount the controller in the generator control panel. Connect wiring for power, sensors, and actuators. Configuration is performed via the front panel or with Basler’s free configuration software. The controller includes a wizard for quick setup of engine parameters and protection thresholds. Commissioning involves testing start/stop sequences and protection functions.

Reliability and Quality

Basler Electric’s DGC‑2020 is built with automotive‑grade components and is tested for vibration, temperature, and EMC compliance. It features non‑volatile memory for settings and event logs, and a watchdog timer for fail‑safe operation. The controller is designed for long‑term reliable performance in demanding environments.

Conclusion

The Basler Electric DGC‑2020 digital genset controller offers powerful, flexible, and user‑friendly control for modern generator sets. Its comprehensive features and robust design make it a leading choice for generator OEMs and system integrators.
