 Maximum output current: maximum output current = 3 / (input voltage - output voltage)
 Input voltage: 4.5V-40V (the highest measured limit can reach 40V)
 Adjustment mode: connect the input power supply first(between 4.5V-40V), then use the multimeter to monitor the output voltage and adjust the potentiometer (generally turn the booster clockwise, reverse the buck)

 Tips: 
 Please adjust the required voltage with no load is applied when adjusting the voltage.

 Package:
 5*LM317 module
Adjustable three-terminal voltage regulator module, can replace all three-break voltage regulator modules such as 7805, 7806, 7809, 7812, 7824.
On-board regulated power supply, connect the input end of this module to the cigarette lighter of the car, and adjust the potentiometer.
The output voltage can be adjusted to 1.25V-30V for your mobile phone, MP3, MP4, PSP and many other devices, very simple and convenient.
When need 1.25-60V to charge your electronic device, there only have 12V or 24V battery power, you can use it directly to step down 1.25-30V to solve your troubles.
the front stage of the system is powered . When you input the power supply voltage lower than the voltage you need (1.25V-30V) when you are working on a project, choose it for your best choice.
