Description: Introduction: This is a linear power supply with high cost performance. Its core solution is LM317+TL431 as the benchmark, and uses Toshiba Goodsound high-power tube 2AS1943 to expand the current. Compared with the general LT317 LT1083, it has higher accuracy and better thermal stability. When TL431 is added as the reference voltage regulator, it rises by 1-2 levels, and the noise and ripple are also lower. A good filter capacitor is NOVER gold 6800UF, and the output has a level 1 LC filter to further eliminate high-frequency noise. High-speed tube. Due to the use of high-power tube 2AS1943 to expand the current output, the maximum current can reach 8A. It can easily drive most equipment, of course, because it is a linear power supply, there will be a certain temperature. When the continuous output current is less than 4A, the temperature is about 10-45 degrees. It can be directly installed inside the aluminum chassis and use the bottom of the aluminum chassis to dissipate heat. If the device current exceeds 4A, you must install it on a heat sink not less than 3KG. Otherwise, the high temperature will cause the output tube to burn out. Must have good heat dissipation conditions. Parameter: Input voltage calculation formula: AC input voltage*1.414-DC output voltage= (8-10V Voltage difference) Output voltage: DC 5V/9V/12V/15V/18V/24V (Optional), If you need customized voltage, please contact us. NOTE: We have DIY kit or Finished board (Optional) ◆ DIY kit ---- All parts need you to solder and test it. ◆ Finished board ---- All parts have been welded and tested OK.
