4-Wire PWM Fan Temperature Controller 12V 3A Fan Speed Controller with Temperature Probe Digital Display Module Dual-Display Fan Governor(Water Droplet Head)

JAMHER 4-Wire PWM Fan Temperature Controller Power supply voltage: DC12V Voltage range: DC8-16V (circuit operating voltage, please configure the power supply according to the fan voltage range!)! ) Circuit self consumption: less than 40mA (test value at 12V, for reference only) Fan current: not exceeding 3.5A PWM range: 1-100, ± 0.5% (signal percentage not actual speed) PWM frequency: 25KHZ (± 1KHZ) PWM signal amplitude: 5V (no-load) The maximum readable value on the monitor is 300 × 100 RPM=30000 RPM Temperature measurement range: -9.9-99.9 ℃ Temperature measurement error: The error within the range of 0-50℃ is less than 1.2℃, and the error in other ranges is less than 2℃ Button Description: +"" - "buttons: Switch display while running, increase or decrease values when setting parameters (long press continuously) The "OK" button has three functions: 1. In the running state, short press to enter the inherent output setting, which is the manual speed regulation setting, with a range of 1-100 (%). Short press again to save and exit. 2. In the running state, long press to enter the temperature parameter setting. After entering, use the "+" and "-" buttons to modify the parameters. Short press the "OK" button to switch the setting items. Set the acceleration temperature "L**" and full speed temperature "'H**" in sequence (*represents the number), turn off the temperature "C**", and then short press the "OK" button again to save and exit the settings. 3. After power off, long press the "OK" button and then turn on the power to enter the function settings. Use the "+" and "-" buttons to modify. Short press the "OK" button to confirm and save to exit. This setting is used to modify the PWM output direction to forward/reverse "P1/P-1". Short press the "OK" button again to save and exit.

• Function: This system helps maintain optimal cooling performance and energy efficiency by increasing fan speed when the temperature rises and decreasing speed when cooling demand is low. It allows for automatic or manual adjustment of fan speed based on temperature readings.
• This speed controller only supports four wire PWM fans and can only control 12V four wire fans that support PWM speed regulation! 2510-4P standard specification interface, with a pin spacing of 2.54mm.
• 2 control modes: Provides manual and automatic fan speed control modes, allowing users to flexibly adapt to various cooling needs and environments. This dual-mode system achieves a balance between user control and intelligent automation.
• Temperature probe: The large black dot probe has a wire length of about 40 centimeters (15.75 inches), which can be placed closer to the thermistor or in areas that require precise temperature monitoring, making it more flexible to use. The probe continuously senses the surrounding temperature and sends real-time data to the controller, which is then displayed on a digital monitor.
• It has a digital display that shows the current temperature and fan speed (RPM) in units of 100 RPM, which allows it to adapt and clearly display the speed of high-performance fans, making it particularly suitable for industrial or professional applications that use high RPM fans.
