Core Functions

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

2. Direct PWM drive for Woodward fuel‑control actuators

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

4. Supports isochronous (single‑unit) and droop (parallel gensets) control modes

5. Remote speed setpoint via 4‑20 mA analog input

6. Automatic transfer switch (ATS) control logic for mains‑genset switching

7. Parameter tuning by dedicated Woodward PC configuration software
