4-Wire PWM Fan Speed Controller 12V 3A Digital Display Temperature RPM Controller for PC Case Computer Cooling Fan with Probe

4-Wire PWM Fan Speed Controller 12V 3A Digital Display Temperature RPM Controller for PC Case Computer Cooling Fan with ProbeFeatures1.Support 4-wire PWM fan intelligent speed control, accurate control of fan speed, energy saving and mute2. Built-in temperature and speed display, real-time monitoring of the operating state, intuitive and convenient3.Supports low-temperature shutdown for fans up to 3A, and supports inverse timing fans.4. Small size design, easy to integrate and install, suitable for compact space equipment.5. High compatibility design, suitable for all kinds of chassis air cooling system, easy and reliable installation.ParameterDesign power supply voltage: DC12VVoltage range: DC8-16V (circuit operating voltage, please match the power supply according to the fan voltage range)Circuit self-consumption: less than 40mA (12V test value, for reference only)Fan current: no more than 3.5APWM range: 1-100, ± 0.5% (signal percentage not actual speed)PWM frequency: 25KHZ (± 1KHZ) PWM frequency: 25KHZ (± 1KHZ) PWM frequency: 25KHZ (± 1KHZ) PWM frequency: 25KHZ (± 1KHZ) PWM frequency: 25KHZ (± 1KHZ) 1KHZ)PWM signal amplitude: 5V (no load)Temperature measurement range: -9.9-99.9 ℃Temperature measurement error: 0-50 ℃ range error is less than 1.2 ℃, other ranges error is less than 2 ℃Warm tips:DC12V four-wire fan temperature control speed controller, digital display of temperature and speed, support for 3A or less fan low-temperature shutdown (directly turn off the fan power), support for reverse chronological fan support 10,000 RPM fan speed display (theoretical support for up to 300X100RPM that is, 30,000 RPM)Note: This controller only controls the four-wire standard PWM signal control of the fan speed adjustment, the signal specification is 25KHz 5V, conventional chassis, CPU and many servers 4-wire fan support but can not control the 2-wire / 3-wire fan speed adjustment! Please note that 2 and 3 wire fans are not available!Package includeFan Speed Controller1 (style of your choice)Temperature Probe1
