Degree Controls has released a single fan controller for improving thermal monitoring and fan speed management in electronic equipment. The TC10257 is small form factor, RoHS compliant, DC fan controller with reprogrammable interface. It is intended for those who are designing equipment that uses a single, 24 or 48V DC fan and do not wish to merely run it at full speed, thereby wasting energy and reducing fan life, while producing excess acoustic noise. Implementing this controller will provide fan RPM control, based on sensed temperature. The temperature may be sensed on the controller itself, or remotely, using a thermistor cable, so that the sensing location is made at the most strategic or important location for optimal thermal management.
