Core Functions

1. Dual control modes: isochronous (constant‑speed) for single‑unit stable operation; droop/base‑load mode for multi‑genset parallel load sharing.

2. Advanced digital PID algorithm + adaptive speed filter, optimizing stability for low‑/medium‑speed engines; supports actuator position droop and idle gain adjustment.

3. Comprehensive protection: overspeed protection, actuator stroke limit, load rejection protection, over‑current/over‑voltage self‑diagnosis and fault logging.

4. Supports Modbus‑RTU communication for remote monitoring, parameter tuning, and DCS/PLC system integration.

5. Compatible with legacy 2301A systems; features bumpless transfer and anti‑interference design for harsh industrial environments.
