Core Functions

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

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

3. Supports 4‑20 mA / 1‑5 VDC analog remote speed/load setpoint input for external DCS/PLC system control.

4. Forward‑acting control logic, compatible with proportional electric/hydraulic actuators.

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