Products Description
DEIF SCM-1 Automatic Generator Synchronizing Control Module
DEIF SCM-1 is a microprocessor-based automatic synchronizing module for generator paralleling control. It continuously compares voltage, frequency and phase difference between generator and busbar, and outputs governor and AVR control signals to match parameters before closing the generator breaker.
This compact panel-mount module uses DIP switches and potentiometers for on-site parameter setting, with front LED status indicators. Widely used in diesel generator sets, hydro power and marine power systems, it is a common spare part for power station switchgear maintenance.

FAQ
| No. | Question & Answer |
|---|---|
| 1 | Q:What is DEIF SCM-1? A:It is an automatic synchronizing module for generator paralleling. It matches generator voltage, frequency and phase with the busbar, then triggers breaker close to safely connect generators to the grid. |
| 2 | Q:How to configure SCM-1? A:It is configured via DIP switches and potentiometers on the module, no special PC software required. Users can set allowable voltage/frequency tolerance and breaker advance time. |
| 3 | Q:What is the main risk without synchronizing control? A:Closing breaker out of sync will cause huge impact current, damage generator winding and switchgear, and trigger power grid protection trip. |
