Control Resources Introduces New Fan Speed Control and Alarm

LITTLETON, Mass., Sept. 17, 2007 -- Control Resources' new SmartFan Fusion-9 digital fan speed control and alarm provides more power (9 Amps), and more fan capability (up to 9), than any previous CRI catalog product. Fusion can control fan speed based on temperature, single or dual I2C interface or analog control signal (PWM, 5.0 VDC). In addition, the Fusion offers ATCA compliance for managed or intelligent FRU cooling systems. In order to fully meet the telecommunication industry's first open standard for carrier-grade systems, the Fusion will communicate with shelf management modules via dual IPMBs as specified by AdvancedTCA PICMG 3.0. The control will provide FRU information, individual fan status and temperature readings.

The Fusion accepts dual power feeds in the range from 36 to 75 VDC and regulates fan speed using a buck regulator control circuit. The board monitors tach pulses from the fans to provide fan status. Fusion-9 can control up to 9 fans and has a current rating of 9 Amps at 55 degrees C or less ($141.80 ea/200 - available now). Configuration of the Fusion is settable via I2C interface or options can be set at the factory to your specifications. Special and custom configurations are available. Benefits of using SmartFan include acoustical noise reduction, energy savings, greater product reliability, increased fan life and improved safety.
