Basler DGC-2020 Digital Genset Generator Controller

The Basler DGC-2020 is a comprehensive digital controller for generator sets, combining engine governor, automatic voltage regulation (AVR), and protection functions in a single unit. It is designed for diesel, gas, and gasoline gensets used in standby, prime, and continuous power applications. The DGC-2020 provides precise control of engine speed and generator voltage, while monitoring critical parameters to ensure safe and reliable operation.

The controller features a large, backlit LCD display with a user‑friendly interface for real‑time data viewing, setpoint adjustments, and alarm annunciation. It includes multiple analog and digital inputs/outputs for connection to sensors, actuators, and remote control systems. The DGC-2020 supports CANbus communication for electronic engines and Modbus for SCADA integration. Its compact design allows easy panel or cabinet mounting.

Functional Capabilities

• Integrated governor and AVR: Eliminates separate controllers, reducing cost and wiring complexity.

• Load sharing and paralleling: Allows multiple gensets to operate in parallel with equal load distribution (requires additional hardware).

• Fuel efficiency optimization: Adjusts engine speed based on load (for variable speed gensets).

• Data logging: Records operational data (voltage, current, power, engine parameters) with time stamp.

• Remote monitoring: Via Modbus or optional Ethernet, enabling connection to building management systems.

Typical Applications

• Standby power systems: Hospitals, data centers, and critical facilities.

• Prime power for remote sites: Mining, oil & gas, and telecommunications.

• Marine gensets: Auxiliary and emergency power on ships.

• CHP (combined heat and power) plants: Coordinated control of gensets.

Installation and Configuration

Mount the controller in a panel cutout. Connect the battery power (8‑36 V DC), engine sensors (temperature, pressure, speed), generator voltage and current inputs, actuator outputs (to fuel actuator and AVR), and alarm relays. The controller is configured using the front‑panel menu: set the generator parameters (voltage, frequency, CT ratio), engine protections, and communication settings. The DGC-2020 includes a setup wizard for quick commissioning.

Compliance

This controller complies with IEC 61131‑2, EMC standards, and carries CE and UL marks. It is RoHS compliant.

Conclusion

Basler DGC-2020 provides a complete, integrated solution for genset control, combining engine and generator management in one robust, user‑friendly device, ideal for modern power generation systems.
