The Heinzmann SyG 02 synchronizer unit is a precision device designed for the automatic synchronization of generator sets to island networks or for synchronizing an entire island to the mains. It is compatible with all Heinzmann electronic governors and is suitable for use in demanding industrial and power generation environments.

Key Features:

• Automatic synchronization for generators to grid or islanded systems

• Three-phase voltage detection with frequency and phase angle measurement

• Adjustable phase angle window: ±2° to ±15°

• Voltage detection range: ≤ 80 V AC (synchronization window)

• Synchronization relay: Max 8A at 250V AC

• Adjustable switching delay: 0.5 to 5 seconds

• Output signal: 1 to 9 V DC for governor control

• Supply voltage: 115 or 230 V AC ±10%

• Generator voltage range: 115–440 V AC (phase to phase)

• Frequency range: 50/60 Hz (special versions up to 400 Hz)

• Synchronization time: Approx. 3–15 seconds (installation dependent)

• Operating temperature: –40°C to +80°C

• Weight: Approx. 2.6 kg

• Robust, industrial-grade construction for reliable operation in harsh environments
