Product characteristics
 
Use imported chip aluminum electrolytic capacitor, high Q value and high power inductor. In addition, each board has undergone strict technical testing, and all boards have been tested and sealed with independent anti-static protection bags. Specially designed 2 screw fixing holes. Four pads of input and output are provided with row pin fixing holes, and the spacing is an integral multiple of 100mi, which is convenient for batch application in products;
 
Note: the output voltage will not change until the factory initial blue potentiometer and resistance value are inserted into the input at the limit, and then the knob is turned in the counterclockwise direction, about 7-8 turns

Product parameters
In + input positive in - input negative
Out + output positive out - output negative
Note that the input and output cannot be reversed, which will burn out
 
Matters needing attention
For long-time operation, it is recommended to use the current within 2.5A, and add heat sink (more than 10W output);
Due to the time step-down module, in order to ensure stable output, please keep the limit of 1.5A pressure difference. 
 
Connection mode
1. Welding, directly welding the power line at the input (output) port;
2. The welding pin can be inserted into the pin through the lead or inserted on the hole board; or the pin can be directly welded on the PCB.
Voltage commissioning
Connect the power supply (3-40v), adjust the blue potentiometer knob (generally rotate clockwise to increase the voltage and anticlockwise to decrease the voltage), and use the multimeter to monitor the power output of the box 2 until the required voltage is reached. 
 
Examples of application
1. The vehicle stable voltage power supply can adjust the potentiometer by connecting the input terminal of this module to the cigarette lighter of the car for power supply. The output voltage can be adjusted at 1.25-30v at will. It can supply power for many devices such as MP3, MP4, PSP charging of your mobile phone, which is very simple and convenient.
2. Supply power to electronic equipment. When the equipment needs 3-35v power supply and the corresponding voltage power supply is in hand, this module can easily adjust the voltage to the required voltage to solve the problem.
3. This module can be used to debug the working voltage range of various voltage testing systems, which is very easy and convenient.
