Adjustable CC-CV DC Step Down 2A Driver QSKJ IN.DC.7-35V OUT.DC.2-30V

Use Original Texas Instruments USA LM2596 Max 3.0 Ampere

High-power LED Adjustable CONSTANT CURRENT driver

Solar Panels and Wind turbines

For LED constant current driver usage:

Make sure operating current and Max operating Voltage of the LED you need to drive.

Adjust the constant voltage potentiometer to make sure the out put Voltage is up to LED Max operating Voltage.

Join LED,test.

(1,2,3,4 steps to connect the power module input and output load does not take LED.)
