Two-way Heat Dissipation PWM Four-wire Fan Temperature Control Governor 12V24V48V Temperature Speed Display Stop Alarm B

Specifications Working voltage DC8 60V must be equal to the fan voltage if you use 12V fan but supply 24V it will burn the fan Working current control board working current 35mA 12V 22mA 24V Control ability not limited by the fan current but the current of the fan interface pin on the board should not exceed 3A If you use a fan with a larger current please connect the fan power cable directly to the main power supply Control output range 10 100 this is only the signal output range the actual situation depends on the performance of the fan Temperature probe specification NTC 10K B 3950Temperature measurement 9 9°C to 99 9°C error 2°C 1 probe within 70°C 3°C above 70°C Temperature control zone range accelerated temperature 5 94°C full speed temperature 10 99°CSpeed measurement 10 9990 rpm if the speed is greater than this it will always display 999 the resolution is 10 rpm and the display unit is 10 rpm the speed measurement is designed according to the common 2 pole signal fan most fans are 2 pole signal Stopping alarm speed below 375rpmCircuit size 65mm 65mm 15mm positioning hole center distance 56mm 56mm diameter 3 2mmWeight The main board a pair of 1 meter wire cylindrical probes total about 40g and the weight of the main board alone is about 23g Features 1 DC8 60V wide working voltage range here refers to the control board can work within this voltage range in actual work the controller power supply and the fan are together so p
