Details

Description:
Board core components: adjustable regulator ASIC LM317- 2A or less can be loaded- AC or DC voltage input- the output voltage is 1.25V-28V DC continuously adjustable- versatile DC board.
Using double adjustment potentiometer: when using LM317T for adjustable power supply- often lead to output voltage increases and burned the load due to potentiometer poor contact. We designed this regulator board using double potentiometer to ensure good contact- effectively protect the load.


Specification:

  • Input: DC 0V ~ 30V / AC 0V ~ 22V
  • Output: DC 1.25V ~ 28V
  • Output current: 2A Max.
  • The minimum differential between input and output: 3V- input must be higher than the output voltage above 3V to be regulated. Buck- not boost- when input 5V output 1.25V ~ 2V- not 6V.
  • Circuit board size: 69 x 50 x 27mm (L x W x H)


Note:
Due to the digital voltage display module operating voltage is 3V- only when the voltage is higher than 3V to display properly
Package list:

  • 1 x LM317 adjustable voltage regulator step-down power supply module with LED meter
