SmartFan Fusion DC Fan Speed Control and Alarm |
 |
 |
 |
 |
|
SmartFan Fusion provides more power (9 Amps), more DC fan speed control and alarm capability (up to 9) than any previous CRI catalog product. In addition, the Fusion offers the features & flexibility of its predecessor, the SmartFan Multi-SR, plus ATCA compliance for managed or intelligent FRU cooling systems. In order to fully meet the telecommunications 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 fan speed control commands and regulates fan speed using a buck regulator control circuit. The Fusion can also be configured to control fan speed based on temperature, I2C commands (single or dual) or analog control signal (PWM, 5.0 VDC). Configuration of the Fusion is settable via I2C interface or options can be set at the factory to your specifications
