Cirrus-6 Datasheet

SmartFan® Cirrus-6 is an off the shelf, customer programmable fan controller designed to manage and monitor up to six 12, 24 or 48VDC 4-wire fans or blowers. Users can create their own temperature control curve, temperature alarm trigger point, low speed alarm trigger point, fail safe modes and more. For autonomous temperature control, the SmartFan Cirrus-6 can be configured using the Navigator PRG00-F hand-held, menu-driven remote programmer (pictured above).  For systems with I2C, the Cirrus-6 offers options to adjust temperature control and alarm parameters or directly control fan speed.  Factory customization available for orders as low as 50 pieces.
