When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

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 ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

In most fan systems a single fan is selected for the required system design rating. Various methods of control are employed such as dampers, variable inlet vanes, variable pitch blades, or variable ...

Proper selection of component fans used in HVAC equipment continues to be a primary consideration in strategies to increase cooling efficiencies in data centers. Newer fan technology and pending fan ...
