3 Channel LM317 Adjustable Power Supply Module
3 Channel LM317 Adjustable Step Down Power Supply Module
Feature:
- 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.
