<br />
<br />Adjustable regulator module with LED display.
<br />2A or less can be loaded, AC or DC voltage input.
<br />The output voltage is 1.25V-28V DC continuously adjustable, versatile for DC board.
<br />Using double adjustment potentiometer to ensure good contact, effectively protect the load.
<br />With LED digital display voltage, the output voltage at a glance.
<br />Very suitable for school students to do experimental use
<br />Notice:
<br />The minimum differential between input and output is 3V;
<br />the input must be higher than the output voltage above 3V to be regulated.
<br />Buck, not boost, when input 5V output 1.25-2V, not 6V.
