Overview

The Woodward 5437‑845 Board‑Notch Filter is a specialized electronic module designed to eliminate interference around the 3 kHz frequency range. In complex control systems such as NetCon®, MicroNet™, and MicroNet Plus, multiple actuator modules can generate “beat” frequencies near 3 kHz. This filter suppresses those signals, preventing noise within the chassis and ensuring reliable operation of turbine and generator controllers.
