III. Main Functional Characteristics

1. Classic Dual Mode Speed Regulation (Core Function)

Isochronous speed regulation (Isochronous): Precise constant speed control, suitable for single-machine operation or multi-machine parallel operation in islanded grid, ensuring absolute frequency stability.

Droop speed regulation (Droop): Parallel load distribution, achieving automatic load balance among multiple units through speed drop characteristics, with extremely strong stability.

2. Precise Load and Synchronization Control

Load management: Supports base load, peak load, soft loading / unloading, load transfer, with an allocation accuracy of **±0.5%**.

Automatic synchronization: Built-in synchronizer, automatically matching voltage, frequency, and phase to achieve seamless grid connection without impact.

Start-up protection: Over-start fuel limit, idle control, critical speed avoidance, protecting engine safe startup.

3. High-reliability Industrial Design

All I/O channels are electrically isolated, with industrial-grade EMI/EMC protection, suitable for strong interference environments.

Wide temperature and vibration resistance: -40°C to + 85°C wide temperature, military-grade vibration resistance, MTBF > 500,000 hours.

Dual serial port communication: RS-232/422 independent dual ports, supporting remote monitoring, parameter configuration, and fault diagnosis.
