DEIF SCM-1 | SCM-2 synchronization control module
The DEIF SCM-1 is a microprocessor-based synchronization control module designed for precision paralleling of generators in marine and industrial power systems. As part of DEIF’s GPC-3000 power management platform, this IEC 61892-certified module enables seamless load sharing between multiple gensets with ±0.25% voltage matching accuracy. The SCM-1 implements advanced cross-current compensation algorithms to maintain <1° phase angle synchronization during black start operations in offshore platforms.
Featuring dual redundant CANopen interfaces, the DEIF SCM-1 supports J1939 and Modbus RTU protocols for integration with PLCs like Allen-Bradley 1756-L82E or Wärtsilä UNIC C3 systems. Its 24-bit DSP processor calculates 50/60Hz parameters within 10ms cycle time, critical for hospital standby power switchovers. The module’s 4-layer PCB design with conformal coating withstands 97% humidity in tropical marine environments.

Key Features and Advantages:
Advanced load anticipation: The SCM-1’s predictive algorithm reduces reverse power risk by analyzing prime mover torque characteristics before closing circuit breakers in data center power plants.
Multi-bus synchronization: Simultaneous monitoring of 3 independent busbars enables complex islanding scenarios in naval vessels. Built-in harmonic distortion analyzer (<2% THD measurement) prevents resonance issues during turbine generator paralleling.
User-programmable curves: Create custom synchroscope characteristics for legacy switchboards using DEIF WinGPS 2.3 software. The front-panel OLED displays vector relationships with 0.1° resolution for quick verification on drilling rig power stations.
Application Areas:
The DEIF SCM-1 is essential in:
- Marine: Synchronizing 690VAC/60Hz gensets on cruise ships
- Oil & Gas: Managing 11kV offshore platform microgrids
- Utilities: Black start coordination for hydroelectric plants
- Construction: Mobile power station load sharing
In LNG carrier electrical systems, the module maintains 400VAC/50Hz synchronization during dynamic positioning operations. Mining operations utilize its vibration-resistant design (5g @ 10-150Hz) for diesel generator paralleling in mobile processing plants. The IEC 60068-2-6 certified shock resistance ensures reliability in wind farm service vessels.
