Core Functions

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

2. Forward‑acting control logic, compatible with standard proportional electric‑hydraulic actuators.

3. PID closed‑loop control with startup ramp, actuator stroke limit, load rejection protection and overspeed test function.

4. Supports 4‑20 mA analog remote setpoint input for speed/load adjustment, compatible with DCS/PLC systems.

5. RS‑485 Modbus‑RTU communication for real‑time monitoring and parameter configuration.
