DU-2/MKIII Generator Control Unit

Advanced Generator Control Unit for Marine and Industrial Applications

Technical Specifications

Main Features and Advantages

Comprehensive Generator Protection: The DEIF DU-2/MKIII provides advanced monitoring and protection for generator sets with 10+ protection functions including under/over voltage (adjustable 70-130%), frequency deviation (adjustable 80-110%), reverse power (adjustable 5-25%), and phase sequence monitoring. Its fast-acting relays trigger within 100ms of fault detection, preventing equipment damage in critical power applications.

Intuitive User Interface: Featuring a high-contrast graphic LCD display, the unit provides real-time visualization of generator parameters including voltage, current, frequency, power factor, and active/reactive power. The menu-driven interface simplifies configuration with password-protected access levels, while event logging stores 100+ time-stamped alarms for post-fault analysis.

DU-2MKIII

Marine-Grade Durability: Designed for harsh environments, the DEIF DU-2/MKIII meets stringent marine certifications including DNV-GL, ABS, and Lloyd’s Register. Corrosion-resistant terminals and conformal-coated PCBs withstand saltwater exposure, while -25°C to +70°C operational range ensures reliability in extreme conditions.

Flexible Control Capabilities: Six configurable relay outputs enable sophisticated control strategies for generator start/stop sequences, load sharing, and synchronization operations. The DEIF DU-2/MKIII supports both manual and automatic modes with configurable timers and interlocks, providing operational flexibility across diverse applications.

Seamless System Integration: With native Modbus RTU and CAN bus interfaces, the controller integrates with PLCs, SCADA systems, and power management software. Two analog outputs provide real-time power parameters to chart recorders or external displays, while configurable I/O mapping enables custom control schemes.
