12V 4-Wire Fan Temperature Control Speed Controller Reduction Module

12V 4-Wire Fan Temperature Control Speed Controller Reduction Module Description

Description: 1. The product is made of high-quality 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 attached cylindrical probe is more suitable for liquids and other situations. If you need to bring your own probe, please note that the probe resistance is 10K and the B value is 3950!
note: Different batches may have slight color differences or differences in the actual product, which does not affect use.
Material: PCB+electronic components
colour: Black
