Adjustable regulator module with AC or DC voltage input, the output voltage is 1.25V-28V DC.    

Features:    
Adjustable regulator module with LED display.    
2A or less can be loaded, AC or DC voltage input.    
The output voltage is 1.25V-28V DC continuously adjustable, versatile for DC board.    
Using double adjustment potentiometer to ensure good contact, effectively protect the load.
    
Notice:    
The minimum differential between input and output is 3V; the input must be higher than the output voltage above 3V to be regulated.    
Buck, not boost, when input 5V output 1.25-2V, not 6V.
