It allows for automatic or manual adjustment of fan speed based on temperature readings.\u003c\/li\u003e\n\u003cli\u003eThis 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.\u003c\/li\u003e\n\u003cli\u003e2 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.\u003c\/li\u003e\n\u003cli\u003eTemperature probe: The circular probe has a wire length of about 50 centimeters (19.69 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.\u003c\/li\u003e\n\u003cli\u003eIt 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.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eJAMHER 4-Wire PWM Fan Temperature Controller\n\nPower supply voltage: DC12V\nVoltage range: DC8-16V (circuit operating voltage, please configure the power supply according to the fan voltage range!)! )\nCircuit self consumption: less than 40mA (test value at 12V, for reference only)\nFan current: not exceeding 3.5A\nPWM range: 1-100, ± 0.5% (signal percentage not actual speed)\nPWM frequency: 25KHZ (± 1KHZ)\nPWM signal amplitude: 5V (no-load)\nThe maximum readable value on the monitor is 300 × 100 RPM=30000 RPM\nTemperature measurement range: -9.9-99.9 ℃\nTemperature 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℃\n\nButton Description:\n+\"\" - \"buttons: Switch display while running, increase or decrease values when setting parameters (long press continuously)\nThe \"OK\" button has three functions:\n1. 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.\n2. In the running state, long press to enter the temperature parameter setting. After entering, use the \"+\" and \"-\" buttons to modify the parameters.
