10pcs USB 5V to 1-24V Voltage Regulator 3.3V 9V 12V 24V Step up/down Module
Feature:
-Using numerical control technology, adjusting voltage by keys
-It's very convenient to use. You can output 1.0V-24V adjustable voltage by inserting USB.
-One-click on/off output
-Power-off storage before power-off
-Voltage and current can be self-calibrated
Function:
-Press ON/OFF button to turn on/off the output.
-Short press SW button, switch display output voltage, current or alternate display;
-Press any button for 2 seconds to activate voltage regulation and voltage flicker. Press SW button to increase voltage, ON/OFF button to reduce voltage, support long press (fast increase/decrease), wait for 2 seconds to exit automatically after adjustment is completed.
-Press the ON/OFF button for 5 seconds, turn off the digital tube and wake up with any button.
-This module has various soft protection functions, when the output voltage is below 0.8V, there will be undervoltage protection (LVP); when the output current exceeds 2A, there will be overcurrent protection (OCP); when the overpower is used, there will be overpower protection (OPP); after protection, the output will be automatically closed and the corresponding protection code (LVP/OCP/OPP) will be displayed.
Note:
This module is not a high power supply, please use it in the power range.
Output power = output voltage * output current
Output voltage 1V-2V, 2W use;
Output voltage 2V-24V, 3W use.
Voltage accuracy: ±0.5%+1 byte, resolution 0.1V
Current accuracy: ±1%+2 bytes, resolution 2ma-10ma
Voltage and current can be self-calibrated:
Press any button and power the product. After 5 seconds, wait for the digital tube to display `8.8.8'. Then enter the self-calibration mode. Voltage flickers. Voltage is calibrated by pressing `ON/OFF'and `SW' buttons. After 2 seconds of pressing any button for a long time, current flickers. Current is calibrated by pressing `ON/OFF'and `SW buttons for a short time. After the calibration is completed, after pressing any button for 5 seconds, the calibration mode is withdrawn.
