Product Description: LM2596 step-down converter 3,2V-35V 3A with display
LM2596 step-down converter module. Input voltage from 3.2 V to 40 V. Maximum continuous output current 3 A. Output voltage adjustable from 3.2 V to 35 V.
Directions of use
The module has four leads as screw connectors:
| PIN | DESCRIPTION |
|---|---|
| IN+ | Input voltage – positive pole. |
| IN- | Input voltage – negative pole (ground). |
| OUT+ | Output voltage – positive pole. |
| OUT- | Output voltage – negative pole (ground). |
The output voltage is selected from 3.2 V to 35 V using a potentiometer. Note that this is a voltage step-down circuit, so the output voltage cannot be higher than the input voltage.
Features:
- Input: DC 3.2 V to 40 V (input voltage must be higher than the output voltage)
- Stable output, the output voltage is DC 3.2V to 35V, continuously adjustable, maximum output current is 3A.
- LED indicator output.
- Adjust the screw on top of the potentiometer clockwise or counterclockwise to increase or decrease the output voltage.
- With reversed polarity protection and short circuit protection, more safer to use; the display is very accurate.
