LM317 Adjustable Voltage Regulator Step Down Power Supply Module with Display

Overview:

The module comes fitted with and adjustable ASIC LM317 regulator, with 2A or less current that can be loaded, AC or DC voltage input. The output voltage is 1.25V-28V DC.

Specification:

• Input: DC:0-30v / AC:0-22V
• Output: DC 1.25-28V
• Output current: 2A(Max)
• The minimum differential between input and output: 3 volts; 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.
• Size:. 69 x 50 x 27mm (L x W x H)

Note: The digital voltage display module operating voltage is 3V. Only when the voltage is higher than 3V, the module will display properly.
