DEIF SCM-1 Synchronism Check Module

Synchronism Check Module for Generator Paralleling Systems

Technical Specifications

Main Features and Advantages

Precision Synchronization Control: The DEIF SCM-1 ensures safe generator paralleling with ±0.5° phase angle accuracy. Its advanced vector measurement technology continuously monitors voltage magnitude, frequency, and phase relationship between generator and busbar, preventing out-of-phase closures that cause catastrophic equipment damage.

Adaptive Closing Logic: The module’s intelligent algorithm calculates the precise moment for breaker closure based on real-time slip frequency measurements. Adjustable parameters for voltage differential (0-20%), frequency differential (0-1.0Hz), and phase angle limit (0-30°) allow customization for specific application requirements while maintaining grid safety standards.

Visual Synchronization Feedback: The integrated synchroscope display provides clear visual indication of phase relationships through LED indicators. This intuitive interface simplifies operator decisions during manual synchronization procedures while automatic mode enables unmanned operations with configurable dead-bus and live-bus detection.

Robust Marine-Grade Construction: Designed for harsh environments, the DEIF SCM-1 meets stringent DNV-GL, ABS, and Lloyd’s Register certifications. Corrosion-resistant terminals and conformal-coated circuitry withstand saltwater exposure, while -25°C to +70°C operational range ensures reliability in extreme conditions.

Seamless System Integration: With universal 100-480V AC input compatibility, the module connects directly to generator and busbar potentials without additional transformers. Two configurable relay outputs provide flexible control signaling for breaker closure commands and alarm indications, compatible with all major switchgear systems.
