2Pcs 4-Wire Fan Temperature Speed Controller Module Board YR-1001 DC12V Fan Speed Controller Temperature Control Module

YR-1001 temperature fan controller is an intelligent fan controller that can accurately control the speed of the fan. Automatically detect the machine temperature and control the fan speed in real time, achieving effective cooling effect while ensuring the safe and stable operation of the equipment. The controller also has a temperature sensor fault diagnosis function. When a sensor problem is detected, the screen will display CER to remind the user, preventing equipment damage or accidents caused by overheating. Product parameters Design power supply voltage: DC 12V Voltage range: DC10-14V (please pay attention to the fan voltage range for circuit operating voltage) Circuit self consumption: less 30mA (tested at 12V) Fan current: cannot exceed 4A, can directly turn off the fan power PWM frequency: 25KHZ (duty cycle 0-100%) PWM amplitude 5V Temperature measurement range: -5°C to 99.9°C Temperature measurement error: The error within the range of 0-50 ° C is less ± 1 ° C, and the error in other ranges is less ± 2°C Circuit board size: 50mm * 27mm (length and width mm, excluding protruding interfaces) Button Description Settings: Enter parameter settings (press and hold for 3 seconds while working to restore factory settings) Add key: Increase the value (in working state, press this key to quickly manually adjust the fan speed, press the setting to exit) Minus button: Reduce the value (in working state, press this button to quickly manually adjust the fan speed, press the setting to exit) Parameter settings Lightly press the settings button to enter settings.
