UMLIFE 2PCS 4-Wire PWM Fan Temperature Controller with Temperature Probe Digital Display ℃ Temperature Controlled Governor, Digital Display ℃ Temperature Controlled Governor for 3A Fan PC, DC 12V

4-Wire PWM Fan Temperature ControllerPower supply voltage: DC12VVoltage 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 3.5APWM 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 RPMTemperature 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.

• Rate Monitoring: The 12v pwm fan controller is equipped with a digital display that shows the current temperature and fan speed in real time. The rotational speed (RPM) is displayed in units of 100, with a maximum readable value of 30,000 RPM (300 x 100). This makes it particularly suitable for industrial or professional applications that utilize high-speed fans
• Designed for 4-wire PWM fans, this 12V3A temperature-to-speed display controller ensures your fan operates at optimal speed, adjusting as temperatures change. For reducing noise in PC cases and servers while enhancing energy efficiency.
• With the capability to display RPMs in increments of 100, up to a maximum of 30,000 RPM, this PC fan controller for applications requiring high-speed fan operation. Monitor and control your fan's speed with accuracy, ensuring your system stays cool, even under the most strenuous conditions
• Note: this controller is exclusively designed for 4-wire PWM signal controlled fans, conforming to the 25KHz 5V signal standard. It's compatible with conventional PC cases, CPU fans, and many server fans. However, it cannot control 2-wire or 3-wire fan speeds, ensuring your setup meets these specifications for optimal performance.
• Temperature Probe: This fan speed controller regulator features a 42 cm (16.54 inch) probe that continuously monitors ambient temperature and transmits data to the controller for display on the digital screen.The fan temperature probe is an NTC 10K / 3590
