Four-wire PWM fan thermostat computer cooling, fan temperature control module automatic temperature control speed DC 12V

   Four-wire PWM fan thermostat computer cooling, fan temperature control module automatic temperature control speed DC 12V

  Computer cooling four-wire PWM fan automatic temperature control speed control 1 channel temperature control 2 channel manual

  Feature:

Support all internal 12V 5A fans, synchronous rectification output, high efficiency! Even high current operation does not require an additional heat sink! Multiple fans can be used in parallel (total current does not exceed 5A), support automatic temperature control and air cooling speed control, the temperature control speed has four temperature zone settings, easy to apply to various applications! It can be turned on with the three-wire fan monitoring function (stall warning).Function setting switch description:

  TFL (No. 1): The minimum PWM setting of the temperature control channel. The FAN1 minimum PWM is 40% in the ON state and the FAN1 minimum PWM is 20% in the OFF state.

  TP1 TP2 (No. 2, 3): The temperature control channel controls the temperature zone. The specific settings are as follows (required with temperature probe):

  TP1 TP2 acceleration temperature full speed temperature

  OFF OFF 35°C 45°C ON OFF 40°C 55°C

  OFF ON 50°C 70°C

  ON ON 60°C 90°C

  Below the acceleration temperature, the output is at the lowest speed. When the temperature exceeds the full speed, it is always output at full speed.

  BF1 BF2 (No. 4, 5): Corresponds to the FAN1 FAN2 stop alarm function switch. When the corresponding fan is turned on, the channel fan will stop and the controller will sound (requires a buzzer) to light the alarm. The alarm is automatically eliminated. If both BF1 and BF2 are ON (ON), then either or both of FAN1 and FAN2 will stop and the controller will alarm!
