WOODWARD 9905-068 2301A Load Sharing and Speed Controller Module – 2301A Series
Imagine a power plant or industrial facility where multiple generator sets must share load in perfect synchrony — without a reliable load sharing and speed controller, even a momentary imbalance can cascade into frequency deviation, generator tripping, or catastrophic equipment damage. In mission-critical environments such as offshore platforms, data centers, and continuous-process plants, unplanned downtime is not measured in inconvenience but in millions of dollars per hour. The WOODWARD 9905-068 2301A is the precision instrument that prevents this scenario, delivering deterministic speed governance and proportional load sharing that keeps your prime movers running in lockstep.
The 9905-068 is a specific hardware configuration within WOODWARD’s legendary 2301A Load Sharing and Speed Control family — one of the most widely deployed governor platforms in global power generation and industrial turbomachinery. Since its introduction, the 2301A series has become the de facto standard for isochronous load sharing on diesel gensets, gas turbines, and steam turbines across more than 100 countries. The 9905-068 variant is engineered for applications demanding robust analog control with proven field reliability, making it a preferred choice for both OEM integration and retrofit upgrades on legacy installations.
