Core Functions

1. High‑precision closed‑loop speed regulation, maintaining stable frequency under variable loads

2. Supports isochronous (zero‑droop) for standalone gensets and droop control for parallel‑running units

3. Remote speed/load setting via 4‑20 mA / 1‑5 Vdc analog input

4. Built‑in overspeed protection, fault self‑diagnosis and alarm output

5. Compatible with Woodward standard fuel actuators, direct control of fuel valves

6. Parameter tuning via dedicated Woodward configuration software
