IN+input positive pole IN - input negative pole!
OUT+output positive OUT - output negative!
Note that the input and output cannot be reversed. Reverse connection may burn!
Input: DC 3.2V to 40V (the input voltage must be more than 1.5V higher than the output voltage. Voltage rise is not allowed)
Output: DC 2.5V to 35V voltage is continuously adjustable, and the maximum output current of high efficiency is 3A.
Features: Solid state capacitor, 36u thickened circuit board, high Q value high power inductance with output LED indicator
For long-time operation, it is recommended to use the current within 2.5A. If the current exceeds 2A, heat sink shall be added (output above 10W);
As it is a step-down module, please keep the minimum 1.5V differential pressure to ensure stable output.
Connect the power supply (3-40V), adjust the blue potentiometer knob (generally rotate clockwise to increase voltage and counterclockwise to decrease voltage), and use a multimeter to monitor the output voltage until it reaches the required voltage
Wiring mode
1. Welding: directly weld the power cord to the input (output) port;
2. The welding pin can be inserted into the pin through the lead or inserted into the hole plate for use; Or it can be directly welded on PCB after adding pins.
Application examples
1. The vehicle mounted stabilized voltage power supply can adjust the potentiometer just by connecting the input terminal of this module to the cigarette lighter for power supply, and the output voltage can be adjusted at 2.5-30V at will, providing power for your mobile phone, MP3, MP4, PSP charging and many other devices, which is very simple and convenient.
2. Power the 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. System working voltage test. This module can be used to debug the working voltage range of various voltage test systems when doing projects, which is very easy and convenient.
