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.
