Description de DC 12V 4 Wire PWM Fan Temperature Control Governor Digital Display

DC 12V 4 Wire PWM Fan Temperature Control Governor Digital Display
Description: 1. The product is made of materials with guaranteed quality
2. The product is designed with ultra small size, and compact, with digital display
3. Support four-wire fan speed regulation, product shipped with probe cable
4. Support low-temperature shutdown of fans up to 3A, to directly turn off the fan power, and support reverse timing fans
5. Stable product performance and long service life
Parameters:
Design power supply voltage: DC12V
Voltage range: DC8-16V (circuit working voltage, please pay attention to the fan voltage range)
Circuit self consumption: less than 40mA (tested at 12V)
Fan current: not exceeding 3.3A
PWM range: 1-100 (signal percentage non actual speed 0.5%)
PWM frequency: 25KHZ (plus or minus 1KHZ)
PWM signal amplitude: 5V (no-load)
Temperature 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
Note:
This speed controller only supports 4-wire PWM fans, and does not support 2-wire and 3-wire fans.
The included large black spot probe is relatively suitable for air detection. If you need to bring your own probe, please note that the probe resistance is 10K and the B value is 3950!
