PWM Fan Controller / SmartFan® Cirrus 6

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 is available for orders as low as 50 pieces.

  • PWM Fan Control for up to Six 4-wire DC Fans or Blowers
  • Temperature or I2C control options
  • Easy setup via Navigator Programmer or I2C bus
  • Factory customization for orders as low as 50 Pieces
