The SID-2SL-A(B) Multi-Function Synchroscope is a high-performance microprocessor-based synchronization instrument supporting up to 16 synchronization points. It features both manual and automatic synchronizing interlocking functions, providing fourfold interlock protection based on voltage difference, frequency difference, phase angle difference, and power angle, ensuring safe and reliable grid connection.

The device supports real-time display of system-side and incoming-side voltage and frequency, as well as various differential parameters, and provides multiple sets of independent high-capacity interlocking outputs.

Equipped with automatic phase-angle compensation, self-diagnostics, and dead-voltage closing interlock, the SID-2SL-A(B) adopts a user-friendly bilingual (Chinese/English) interface. It is widely applicable to synchronization monitoring scenarios with multiple connection points in power plants and substations.
