Note that input and output can not be reversed . Reverse might burn !

Input:DC 3V to 40V (Input voltage must be output voltage higher than 1.5v or more. Not boost)

Output:DC 1.5V to 35V adjustable voltage ,high efficiencyThe maximum output current of 3A.

Features :All useSolid capacitors , 36uThick boardHigh Q value inductor with output power LED indicator

Size :45 ( L) * 20 ( W) * 14 (H ) mm ( including potentiometers )

Precautions:Work long hours is recommended in current use 2.5A or less , while adding fins (10W output above ) ;Because it is buck module , in order to ensure stable output , keep a minimum 1.5V differential .

Voltage Regulator

Access to power supply (3-40V), adjust the blue potentiometer knob (generally clockwise rotation boost , counterclockwise rotation Buck) and with a multimeter to monitor the output voltage reaches the required voltage.Wiring

1. welding , welded directly to the power line input (output ) port ;2. solder pins , can be inserted through the lead insertion pins or plates used in the tunnel ; soldered directly to the PCB or add pin after another .

Application Examples

1. The vehicle power supply, input termination module only need to present the car cigarette power point , you can adjust potentiometer, the output voltage can be adjusted in 1.25-30V, for your phone , MP3, MP4, PSP charging many equipment supply , very simple and convenient.

2. The power to the electronic device when the device needs 3-35V power supply while the hands of the corresponding voltage power supply , with this module you can easily put the voltage to the desired voltage and solve problems.

3. The system voltage test, you can use this module to do the project when debugging a variety of voltage test system operating voltage range , very easy and convenient.
