供应BYDS系列风门旁通控制开关

产品介绍：

The Series BYDS B** Damper Switch is designed to control motorized b** dampers. As individual zone dampers open and close, the system static pressure will rise and fall. In order to maintain proper airflow and static pressure through the HVAC system, a b** system incorporating a floating t*e motorized damper and a static pressure control should be incorporated. A t*ical on/off pressure switch cannot operate in this application due to the high cycle rate that would result, eventually causing contact burnout. The BYDS static pressure control is equipped with a solid-state switching and timing circuit to enhance operation and improve long-term reliability in this demanding application.
