Core Functions

1. Multiple operation modes: isochronous (constant‑speed), droop, base load, peak shaving, suitable for single‑unit and multi‑genset parallel island‑grid operation.

2. Digital PID adaptive control algorithm, effectively eliminating speed hunting during load switching, improving system stability and anti‑interference ability.

3. Rich I/O interfaces: MPU speed input, actuator drive output, analog input/output, digital switch input, relay output, meeting engine monitoring and protection needs.

4. Communication interfaces: RS‑232, RS‑422/485 Modbus‑RTU, supporting PC parameter configuration, remote monitoring and DCS/PLC system integration.

5. Comprehensive protection & fault diagnosis: overspeed protection, actuator stroke limit, over‑current/over‑voltage protection, built‑in fault logging function.

6. Software configurable forward/reverse acting output, compatible with various proportional actuators.
