Main Functions

1. Precise speed‑governing drive: Receives signals from speed controllers to drive fuel actuators, realizing isochronous speed control and droop control for unit grid‑connection and load sharing.

2. Start fuel limiting: Built‑in fuel limit for cold start, reducing black smoke and protecting engines.

3. Dual‑dynamic regulation: Adjustable dual‑dynamic parameters for idle speed, high speed and sudden load change conditions.

4. Built‑in position feedback: With torque feedback; automatic fuel cut‑off and shutdown upon power loss for safety protection.

5. System linkage: Compatible with WOODWARD 2301A, 505, EPG governors and magnetic speed sensors; supports remote control via DCS/PLC.

Product Advantages

1. All‑electric design without hydraulic system: No hydraulic station or connecting rods needed, easy installation and low maintenance cost.

2. Strong anti‑interference capability: Industrial‑grade anti‑EMI performance, suitable for harsh environments such as mining, marine and oil & gas industries.

3. Wide compatibility: Supports single‑unit independent operation and multi‑unit parallel load sharing.

4. High reliability: Low friction and low inertia design, fast response, low failure rate and long service life.

5. Standard certifications: Compliant with CE and industrial safety standards, applicable to explosion‑proof areas.
