Product 31/62

 This little unit will regulate and adjust power supply. It is an amazing handy item for every electronics bench.Comparing with traditional step-down volt transformer, the DROK LM2596 converter has some outstanding features:

Special design “I” & “O” buttons : two buttons in left side of the voltmeter allows you to monitor both input and output voltage. By pressing the input display button or the output display button, the voltmeter will display input voltage or output voltage.

Two LED indicators: including the green LED which lights on when you measure output voltage,
and the red LED which lights on when you test input voltage.

Two buttons for adjusting output voltage: pressing two buttons on right side of the voltmeter, you can adjust output voltage to exactly the required voltage selected. You can press the “+” or “-” output voltage adjustment button for increasing or decreasing output voltage.

Easy wiring: it is quite convenient for you to use our converter thanks to its easy wiring connection. Simply hooking the converter to your input/output, and everything will get done.
