Woodward 8273‑140 2301D‑EC Digital Speed and Load‑Sharing Controller

Product Description

8273‑140 is the 2301D‑EC microprocessor‑based digital governor from Woodward. It is specially designed for generator‑sets driven by diesel engines, gas engines and turbines. 

The unit executes closed‑loop speed regulation and parallel generator load distribution, supports parameter configuration through upper‑computer software, and can adapt to multiple engine 

speed ranges. The sturdy metal chassis delivers shock‑resistant performance for power‑plant and marine harsh‑condition working environments.3. Technical Specifications
