The 8290-189 Speed Control Model belongs to Woodward’s Electrically Powered Governor platform. It provides precise electronic speed regulation for diesel and gas engine applications. Engineers select this model when stable isochronous or droop control becomes critical. Moreover, the electrically powered design ensures consistent actuator response under varying load demands.
The unit integrates with magnetic pickup sensors for accurate real-time speed feedback. Therefore, generator frequency remains stable during sudden load changes. Its compact industrial enclosure supports panel or engine-mounted installations.
