Control Resources Introduces New Fan Speed Control for
4-Wire Fans |
SmartFan Cirrus-6 is a digital fan speed control and alarm that offers an off-the-shelf cooling solution for 4-wire DC fans and blowers. Cirrus-6 can control and monitor tach pulses from up to six 12, 24 or 48 VDC fans with open collector or 0-12 VDC control signal requirements. The controller accepts fan speed commands (including on/off) and provides individual pass/fail fan status via an I2C interface. The I2C interface also provides temperature readings from an on-board thermistor and EEPROM storage.
The Cirrus-6 can be configured to control fan speed based on temperature or analog control signal (PWM, 5.0 VDC). Configuration of the Cirrus-6 is settable via I2C interface or options can be set at the factory to your specifications. Special and custom configurations are available. ($65.60 ea/200 – available now).
Benefits of using SmartFan include acoustical noise reduction, energy savings, greater product reliability, increased fan life and improved safety.
