Features:

1.The product can only control 5V or 12V standard 4-wire PWM fan, through the PWM signal to control the fan speed, the actual fan speed change by the fan's own design.

2. The product can not speed control 2-3 wire ordinary fan, can not cut off the fan power supply, can not completely shut down the fan.

3. Default settings: basic speed control output Po = 20%, acceleration temperature Tu = 30 ℃, temperature control interval Td = 5 ℃ (35 ℃ full speed), signal positive mode.

3. Please note: The power supply voltage should match the fan voltage. The control and speed measurement wires of the fan should not be connected to the positive pole of the power supply! Otherwise it is easy to cause the product short-circuit burned out!
