SID‑2FY Multiplex Synchronizer is a high‑reliability intelligent synchronizing controller designed for complex grid‑connection scenarios. It supports 1–16 user‑defined tie points, automatically detects slip‑frequency or dead‑bus (closed‑ring) modes, and provides precise frequency and voltage control.

Built with dual hardware–software redundancy, it supports one‑button sequence control for fast synchronization and adapts to voltage inputs of varying magnitudes and phase angles.

With powerful built‑in event logging and disturbance recording, SID‑2FY supports multiple communication protocols—including Modbus, IEC 61850, and IEC 103—and features a multilingual HMI. It is widely applicable to conventional power plants, pumped‑storage stations, synchronous condensers, and other scenarios, ensuring efficient and secure grid‑connection processes.
