Key Features

• Adopts high‑precision digital PID control for stable speed and load regulation

• Supports isochronous (zero‑droop) and droop control modes for standalone or parallel genset operation

• Accepts magnetic pickup (MPU) speed input (1–30 V AC) and 4‑20 mA remote setpoint signals

• Built‑in actuator drive output, directly compatible with proportional electro‑hydraulic actuators

• Integrated protections: overspeed shutdown, valve‑position limit, startup fuel limit, fault self‑diagnosis and alarm

• Compatible with Woodward synchronizer modules, DCS and PLC systems for centralized monitoring

• Rugged industrial‑grade design with wide temperature range, anti‑EMI and anti‑vibration performance
