Basler DGC‑2020 Digital Genset Controller

The Basler DGC‑2020 is a digital genset controller designed for monitoring, control, and protection of generator sets in standby and prime power applications. It accepts voltage inputs from 100 to 480 VAC, covering a wide range of generator configurations. The controller provides comprehensive metering, engine control, protection, and communication capabilities, making it an ideal solution for modern power generation systems.

Key Features

The DGC‑2020 features a backlit LCD display for real‑time metering of voltage, current, frequency, power, and engine parameters. It includes automatic start/stop control, programmable protection (over/under voltage, over/under frequency, overcurrent), and multiple communication ports (RS‑232, RS‑485, and optional Ethernet). It also supports remote monitoring via Modbus protocols.

Technical Specifications

Voltage input: 100‑480 VAC, 50/60 Hz. CT input: 5 A or 1 A. Auxiliary supply: 12/24 VDC. Operating temperature: -20°C to +70°C. Outputs: relay contacts for starter, fuel, and alarm. The controller is designed for panel mounting and includes a rugged front bezel.

Operating Principles

The controller continuously monitors generator output and engine parameters. It initiates automatic starting upon loss of mains power (for standby applications) and controls the transfer switch. Protection functions detect abnormal conditions and initiate alarms or shutdowns. The controller logs operational events and can communicate with a central SCADA system.

Applications

This controller is used in diesel and gas generator sets for standby power, prime power, and co‑generation. It is suitable for industrial plants, hospitals, data centers, and remote power stations.

Installation and Configuration

Mount the controller in a panel cutout. Connect voltage, current, engine, and auxiliary inputs. Configure parameters using the front‑panel keypad or software. Commissioning includes setting protection thresholds and communication parameters.

Maintenance and Reliability

Solid‑state design ensures reliability. Regular inspection of connections and firmware updates are recommended. The controller includes self‑diagnostic features.

Conclusion

The Basler DGC‑2020 digital genset controller offers comprehensive control and protection for generator sets, enhancing operational efficiency and reliability.
