Product Description

Function Description:

 

1. Green terminals to input, output is 4Pin (4Pin fan with a computer docking);

 

2. Operating voltage: DC12V Note: The output is used 4Pin computer fans must DC12V type;

 

3. Board size: 27mm * 16mm;

 

4. Oscillation cycle about 40-50uS (frequency approximately 20-25KHz), that is to say, about every 45 microseconds to output a square wave pulse, because the components precision error, frequency only within a certain range;

 

5. Duty cycle (percentage of total cycle time that is output high) is about 10% -95%;

 

6. Power input with anti-reverse protection.
