About this product
An adjustable step-down (buck) DC-DC converter rated at 3A, with an LCD display for monitoring its output. It accepts a 5 to 23Vdc input and produces an adjustable 0 to 16Vdc output, which is useful for powering low-voltage electronics from a higher DC source. Check the output with a multimeter before connecting sensitive loads.

Frequently asked questions
What input voltage is required for a step-down converter?
The input must be within 5 to 23Vdc and higher than the output voltage you want. A buck converter cannot raise the voltage above its input.
Can I use it to power a 5V device?
Yes. Set the output to 5V using the adjustment, confirm the reading with a multimeter, and then connect the 5V device while keeping the current within 3A.
