Custom China Custom PCB SMD/DIP PCBA Factory PCBA Assembly DC 12V Four Wire 4 wire Thermostat PWM Fan Speed Controller Module Manufacturer

Description:

Intel standardized four-wire fan control protocol, supports all standard four-wire interface chassis fan and CPU fan control,
while more than 95 percent support violent fan speed control, three-way independent control of different functions, with the way
temperature shift and two-way stall detection alarm function (with accessories), the largest single-channel support 12V5A fan, the
entire board supports up to 12V9A total current input

Currently recording uncontrollable four-wire Fan Model Summary:

FFR0612VHE, FFR0612DHE
Dimensions 6038
Non-standard anti-timing fan (reverse adjust speed)

Feature:

Board size: the length and breadth 50mm x 43mm x 13mm, the positioning hole position 44mm x 37mm, 3mm diameter
Operating voltage: DC12V
Circuit load capacity: maximum current per output 5A, the bus currents up 9A
Output Range: The first channel 20% -100%, or 40% -100% (TFL = ON)
10% -100% of the second path and the third path
Note: The above range only PWM range, the actual fan control effect will vary depending on the fan.
Temperature probe parameters: 50K B = 3950
Thermostat temperature zone error: error depending on the temperature probe, generally 3-5%
Stall alarm minimum speed: 700-800 rpm

Function setting switch Description:

TFL (No. 1): PWM channel with the lowest temperature setting, when ON, the lowest PWM of FAN1 is 40%.
When OFF, the minimum PWM of FAN1 is 20%
TP1 and TP2 (No. 2 and 3): Temperature channel control temperature zones are interpreted as follows (need to match the temperature
probe used):
