Overview
The SYC6714 is a GAC automatic synchronizer module for paralleling diesel and gas generator sets. It monitors the voltage, frequency, and phase angle of both the incoming generator and the bus, then issues speed bias and voltage bias correction signals to bring the generator into synchronization before issuing a breaker close command.
Key Features
- Automatic Synchronization — Microprocessor-controlled sync module that automatically matches generator voltage, frequency, and phase angle to the bus before breaker closure
- ±1% Voltage Matching — Precise voltage regulation with configurable dead-band settings for clean paralleling transitions
- Check-Sync Relay Output — Dedicated breaker-close contact with programmable phase angle window (0–20°) for safe paralleling
- Multi-Generator Support — Daisy-chain capable for synchronizing multiple generators in island or grid-parallel power station configurations
- LED Status Display — Front-panel LEDs indicate sync status, voltage match, frequency match, and breaker close signal for easy commissioning
- Universal Compatibility — Works with GAC, KUTAI, Fortrust, and Cummins electronic speed governors via standard ±3V speed bias input
