Details：

The core is LM317 + TL431 as the benchmark, and use Toshiba Goodsound's high-power 2AS1943 to expand the current. Compared with the general LT317 LT1083, it has higher accuracy and better thermal stability. Adding TL431 as the reference voltage regulator increases 1- 2 levels, lower noise and lower ripple. The cost is not high. Of course, good capacitor, the filter is NOVER gold 6800UF, and the output is equipped with a level 1 LC filter to further eliminate high-frequency noise.

Output voltage: DC5V-DC20V Continuously adjustable. DC24V need change one Resistor, output voltage can not above 25VDC

Output current: max 5A

The input voltage must higher about 7-10V than the output DC. (input voltage = transformer output voltage *1.414)

Transformer ：recommend 120W

PCB Size:100mm*85mm

Height： about 40mm

Package included：

Linear power supply board x 1
