Brushless DC Fan; 4 wire version, with pwm speed control and pulse sensor

DC09733024S1100H

Dynetics 

represents a broad range of axial- and radial-fans with an AC or DC- power supply for equipment cooling with a variety of axial instrument ventilators and radial blowers from leading manufacturers, such as Nidec Servo and Nidec Copal

The fans combine long life with high reliability.

DC09733 series

  • radial fans 
  • sizes 97 x 95 x 33mm. 
  • Are ball bearing based 
  • DC-fans; 
  • the housing and impeller are made from thermoplastic PBT, UL94V-0; 
  • the weight is only 200g,
  •  have an IP21 level, Special IP Rating On Request 
  • CE-approved 

Optional: 

  • a Lock detection: (Suffix “-RD” or “RRD” ) for Rotation Detector Function.
  • a “Speed signal” or speed detection : (Suffix “-FG” ) for a Signal-Frequency Generator Function (also called  for Frequency Generator Function.
  • speed control by PWM: ( Suffix “-PWM”.) for automatic speed Controls via an external input signal.
  • Speed Control by Voltage : speed controll by applying an external DC Voltage signal. from 0V to 10V(standard value is 0 to 5V).The speed will vary linear and is proportional to the % change of the "Vin" value,.
  • Temperature Control: (Suffix “-T” ) with a built in thermistor that detects the ambient temperature, and controls the speed of the fan accordingly.
  • High Temperature Environments: Suffix basic “-HT” for temperature operating ranges -10~90 °C
  • Special IP Rating On Request

We can also customized the fan, like harness wire, different lead length, connector, etc 

are ideally suited for cooling of compact equipment.

PWM CONTROL:

SIGNAL DESCRIPATION:

  • CONTROL SIGNAL: PWM CONTROL

SIGNAL TYPE:

  • INPUT LOW LEVEL VOLTAGE: MAX <0.8V
  • INPUT HIGH LEVEL VOLTAGE: MIN. >2.6V , MAX. <26.4 V
  • PWM FREQUENCY RANGE: 100HZ~100KHZ
  • MAX. SINK CURRENT: 8mA
  • IMPENDANCE : 10K OHM MIN

FAN SPEED CONTROL:

  • FAN INPUT VOLTAGE (POSITIVE) : 24 V PWM FREQUENCY : 25 KHZ
  • THE FAN SPEED SHOULD RUN AT FULL SPEED GIVEN PWM 100% DUTY CYCLE INPUT.
  • THE FAN SPEED MAY RUN AT ZERO SPEED GIVEN BELOW PWM 0 %~15% DUTY CYCLE INPUT
  • THE FAN WILL GO TO FULL SPEED WHEN THE CONTROL SIGNAL IS DISCONNECTED
