Some DC Fans and Blowers offer an optional thermal speed control by the use of a thermistor. There are typically 2 thermistor mounting location options:
- Hub Mount - Thermistor is mounted on the fan hub. With this configuration, the fan senses the temperature of the air as it flows through the fan and adjusts the speed accordingly.
- Remote Mount - Thermistor is mounted on the end of lead wires. The thermistor can be placed in a location away from the fan to sense the ambient temperature and adjust the fan speed accordingly.
As an example, Mechatronics Optional Thermistor DC Fans and Blowers will typically operate at approximately half speed for 25 degrees C or less. At 35 degrees C or greater, the fan will operate at full speed. Between 25 and 35 degrees C, the fan speed will automatically adjust based on the ambient temperature.
Part Numbering
- Thermistor is option 3 or 4
