Additional Special Function:

1. The output of 3rd wire Signal-Rotation Detector Function (also called “Locked signal” or “Alarm Signal”):

   Suffix basic part number with “-RD” or “RRD” for Rotation Detector Function.

   (For AC fan motor only)
   
   (For DC fan motor only)
   
2. The output of 3rd wire Signal-Frequency Generator Function (also called “Speed signal”):

   Suffix basic part number with “-FG” for Frequency Generator Function. 
   　

   (For AC fan motor only)
   
   (For DC fan motor only)
   
3. The output of 3rd wire Signal- PWM Control (Pulse Width Modulation) Function:

   Controls the fan speed automatically via an external input signal.

   Suffix basic part number with“-PWM”for PWM Control Function.

   (For DC fan motor only)
   
4. The output of 3rd wire Signal- VC (Voltage Control) Function:

   With this function the speed can be controlled by applying an external DC Voltage signal.

   This voltage input may have any value from 0V to 10V(standard value is 0 to 5V).

   The fan speed will vary linearly and is proportional to the % change of the "Vin" value,corresponding to the same % change of the maximum speed.

   
5. Temperature Control:

   Suffix basic part number with “-T” for Temperature for operating environments where noise and temperature are a consideration.

   When the built in thermistor detects a drop in ambient temperature, the fan rpm will decrease resulting in a lower noise level and airflow rate.

   Conversely, as the thermistor detects a rise in temperature, the noise level will increase relative to the rise in the fan’s rpm’s until the targeted temperature has been attained.

   
6. High Temperature Environments:

   Suffix basic part number with “-HT” for High Temperature Fans in the following temperature operating ranges are available:

   DC FAN：-10~90 °C -14~194 °F

   AC FAN：-10~180 °C -14~356 °F
