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. Dust and Water Splash Resistant as per IEC IP-54:

    Suffix basic part number with “-54” for Dust Resistant / Water Splash Resistant.

    This unit is protected against splashing water (water spraying at all angles @ 10 liters/min @ a gage pressure of 80-100kN/m2 for 5 minutes).

  7. Dust and Water Jet Resistant as per IEC IP-55:

    Suffix basic part number with “-55” for Dust Resistant / Water Jet Resistant.

    The unit is protected against water jets projected at all angles through a 6.3mm nozzle at a flow rate of 12.5 liters/min at a gage pressure of 30kN/m2 for 3 minutes from a distance of 3 meters.

  8. 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
