Oct 05, 2009 To ensure required linear air velocity is maintained despite external influences, C-600 controls and modulates fan RPM based on real-time air velocity and/or temperature measurements. User-programmable air velocity and temperature set points are leveraged to increase or decrease fan RPM, and I²C- or UART-based communication to host system can relay real-time information. If cooling fan is unable to generate desired flow requirement, controller initiates low-flow alarm to system.
