DC-DC 5V12V24V Automatic Stabilizer Up And Down 5A/80W Regulator Module With Voltage Indicator Adjustable Power Supply Module

Input Voltage: DC 4.5 - 30V not rear or reverse or will be damagedOutput Voltage: DC 0.5 - 33V Aximum Output Current: 5A Max Output Power: 80W long continuous operation please strengthen the heat, best to leave a margin Conversion Efficiency: 91% (measured at 12V input, 19V 2A output) Note: this module is a regulator module, without constant current function, can not output directly to the battery or LED (that is, that the output can not be directly connected to the battery, such as from the battery itself with the charging circuit can be connected, such as the red charging after, the LED drive has no problem)Key Function Details:Quickly press and release (Press duration less than 0.5 seconds) to switch the input and output voltage of the display when the indicator is red when the input is voltage, When the indicator is green, the output voltage press this button for about 1 second - 2 seconds, let go when the monitor is closed, and then press the button again to open the display again. Press this button for more than 2 seconds, let go after the reference voltage voltage indicator, then the default display 3.33 and red light flashing, on behalf of the input is more accurate, short press the button to change the value, the value range is from 3.28 to 3.38. Press the button to change the value, adjust to the corresponding value after Long press the button for more than 1 second, save the benchmark set, and then press the button to change the value, reference voltage, and return to the normal display. (Tip: when the displayed voltage is lower than the actual voltage, when the large reference voltage, when the display voltage is higher than the actual voltage, to adjust the small reference voltage)Reminder: The power module will definitely work, this module naturally cools the power around 60W, for example, for a long time working 80W, it needs to do the right to amplify the heat, otherwise it will be overheating protection. In the case of high voltage current, there may be an inductive sound, which is normal. Size: 7.8x4.7cm/3.07x1.85inchNote: Please allow 1-3mm error due to manual measurement. Pls make sure you do not mind before you bid, due to the difference between different monitors, the picture may not reflect the actual color of the item. Package Included:1x Up and Down Regulator Module
