Core Functions

1. High‑precision closed‑loop speed control to stabilize frequency under variable load conditions

2. Supports isochronous mode for single‑unit constant speed, droop mode for multi‑unit parallel operation, grid synchronization and load sharing

3. Remote speed/load setpoint via 4‑20 mA and 1‑5 VDC analog inputs

4. Integrated overspeed protection, self‑diagnosis and fault alarm outputs

5. Directly drives standard Woodward fuel actuators and turbine control valves

6. Parameter configuration, commissioning and monitoring via dedicated PC software
