Product Overview
The Woodward 9907‑175/A is part of the 2301A Electronic Speed Control series, engineered for diesel engines, gas engines, and steam/gas turbines. It provides precise speed and load regulation in both isochronous (constant speed regardless of load) and droop (load sharing among multiple units) operating modes.
As a forward-acting speed control unit, the 9907‑175/A delivers direct actuator drive signals for accurate fuel or steam flow regulation. It is widely applied in power generation, marine propulsion, and mechanical drive systems, where stable and reliable speed/load control is critical.
