The LM317 AC/DC Adjustable Voltage Regulator Step-down Buck Converter Module with LED Voltmeter is a versatile module for providing regulated DC voltage output. Here are the key features and specifications:
Features:
Adjustable regulator module with LED display.
Supports loading of 2A or less.
Accepts both AC and DC voltage input.
Output voltage is continuously adjustable from 1.25V to 28V DC.
Uses a double adjustment potentiometer for precise voltage control.
Specifications:
Input Voltage: DC 0-30V; AC 0-22V
Output Voltage: DC 1.25-28V
Output Current: 2A (Max.)
Size: 62 x 59 x 27mm
Weight: 42g
Package Includes:
1 x LM317 AC/DC Adjustable Voltage Regulator Step-down Buck Converter Module with LED Voltmeter
Note:
The minimum differential between input and output should be 3V.
Input voltage must be higher than the output voltage by at least 3V for proper regulation.
It performs step-down (buck) conversion, not step-up (boost). For example, with an input of 5V, the output will be between 1.25V and 2V, not 6V.
