LM317 AC/DC Adjustable Voltage Regulator Step-down Buck Converter Module LED Voltmeter

LM317 AC/DC Adjustable Voltage Regulator Step-down Buck Converter Module LED Voltmeter is a module that uses the LM317 IC to provide a regulated DC voltage output. The module also includes a built-in LED voltmeter which displays the output voltage. This is a convenient feature that allows the user to easily monitor the voltage output of the module.

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.

Specifications:

Input Voltage	DC: 0-30V; AC: 0-22V
Output Voltage	DC 1.25-28V
Output Current	2A(Max.)
Size	62 * 59 * 27mm

Package Includes:

• 1 x LM317 5V 12V DC Voltage Regulator Buck Step Down Converter Module LED Voltmeter 

Note:

• 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.
