Dwyer FC-1000型 風機速度自動調節器

美國德威爾FC-1000型風機速度自動調節器 
Electronic Fan Speed Control 
Low Cost, 0-10 VDC Input, Selectable Hard Start 

The Model FC-1000 Electronic Fan Speed Control provides precise speed modulation of small AC motors. Popular 0-10 VDC input works with most process controllers, eliminating the need for more expensive dampers, damper actuators and linkages while improving overall energy efficiency of the system. This inexpensive unit enables variable control ventilation fans, condenser fans and interfacing with VAV box controllers.
