产品名称:  BYDS系列风门旁通控制开关
产品型号:  BYDS系列

产品介绍：

The Series BYDS Bypass Damper Switch is designed to control motorized bypass 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 bypass system incorporating a floating type motorized damper and a static pressure control should be incorporated. A typical 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.
