DELOMATIC-3 DGU2

• “DELOMATIC-3”: Identifies DEIF’s flagship generator control system family, optimized for industrial and marine power management.
• “DGU2”: Stands for “Generator Control Unit (G CU) 2nd-generation,” distinguishing it from legacy DGU1 variants with enhanced processing and connectivity.
• “Integrated Generator Control Unit”: Highlights its all-in-one functionality—combining control, synchronization, protection, and monitoring to eliminate the need for discrete components.
• 

  This module acts as a “generator brain,” orchestrating startup, 并网 (grid connection), and shutdown while safeguarding equipment from electrical faults and ensuring power quality.)

2. Product Description

• Marine Applications: Controlling main generator sets on commercial ships, oil tankers, and cruise ships, where reliable power ensures navigation system stability and passenger comfort.
• Land-Based Power Plants: Managing backup power systems for data centers, refineries, and remote industrial sites, supporting black start (grid-independent startup) during outages.
• Microgrids: Enabling seamless switching between standalone and grid-connected operation, optimizing energy distribution for off-grid communities or industrial parks.
• Critical Infrastructure: Protecting generator sets in hospitals and emergency facilities, with rapid fault response (<50 ms) to avoid power disruption.

Key Functional Advantages

1. Tri-Mode Operation & Precise RegulationSupports standalone, grid-connected, and black start modes ， adapting to dynamic power demands. Equipped with a built-in PID control module, it delivers voltage regulation accuracy of ±0.5% and frequency stability of ±0.1 Hz—critical for powering sensitive equipment like medical imaging machines or ship navigation systems. The dynamic response time ≤50 ms ensures minimal voltage/frequency deviation during load spikes (e.g., sudden activation of shipboard pumps) 。
2. Automatic Synchronization & Load DistributionIntegrates a high-precision automatic synchronizer that matches generator voltage, frequency, and phase with the grid or parallel generators before 并网 —preventing electrical transients that could damage alternators. Its intelligent load distribution algorithm evenly allocates power across multiple generator sets, reducing fuel consumption by 8–12% compared to manual operation 。
3. Comprehensive Protection & Fault DiagnosticsMonitors 10+ electrical parameters (voltage, current, power factor, temperature) and triggers instant protection for overcurrent, overvoltage, undervoltage, overfrequency, underfrequency, and reverse power faults 。 Fault isolation time ≤2 minutes, and the module automatically records event data for post-incident analysis—reducing troubleshooting time by 40%. Dual redundant power inputs with <5 ms switchover ensure uninterrupted operation even if the primary power supply fails 。
4. Multi-Protocol Connectivity & ScalabilitySupports Modbus RTU and CANopen protocols via 2× RS-485, 1× CAN, and 1× Ethernet interfaces ， enabling seamless integration with ship navigation systems, power station SCADA, and DEIF’s own display units (up to 3 DU panels per DGU2). The modular design allows adding I/O expansion modules (DI/DO/AI/AO) without hardware replacement, adapting to generator sets from 500 kW to 2000 kW 。
5. Rugged Design for Harsh EnvironmentsBuilt with an IP65-rated enclosure and industrial-grade anti-interference circuits ， it withstands high temperature (-25°C to +60°C), high humidity (0–95% non-condensing), and dust—ideal for engine rooms, offshore platforms, and desert power sites. The compact 6 TE (30.5 mm width) form factor saves space in densely packed control cabinets 。

5. Typical Application Scenario

• Module Configuration: Each DGU2 connects to a generator, 2 DEIF DU display panels (engine room + bridge), and the ship’s navigation system via CANopen. Redundant power inputs (PSM-1 modules) and Ethernet links are enabled.
• Synchronization & Load Management: When the ship departs, the DGU2s automatically start generators and synchronize them to the main bus in 30 seconds. During peak load (dinner service + cabin AC), the modules distribute 7200 kW evenly across all sets—maintaining 400 V/50 Hz with ±0.2 V deviation.
• Fault Response: A generator experiences overcurrent due to a pump malfunction—the DGU2 triggers an alarm, isolates the faulty unit in 1.5 minutes, and redistributes load to the remaining three sets. No loss of power to cabins or navigation systems occurs.
• Black Start Capability: During a shore power outage, the DGU2s initiate a black start—powering critical systems (navigation, lighting) within 2 minutes using one generator, then bringing others online sequentially.
