產(chǎn)品介紹：

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.
