HiFi Linear Power Supply Board Kit DC5V-DC24V Low Noise PSU For Audio Device

Description: Details:This is a high-current DC voltage stabilizing circuit, using Xinyen high-power rectifier bridge, LM317 and TL431 as the voltage reference, with Toshiba high-current tube A1943 as the output transistor, and CLC filter decoupling circuit. It features good output linearity under high current, stable voltage, wider bandwidth than LT1083CP, and excellent cost performance.By replacing the trimming potentiometer, it can be used for 3.3V-36V power output, which is very suitable for notebook power supply, NAS hard disk box and other linear power upgrades.When the load current is less than 1A, the rectifier bridge and output tube on the board can be installed with a small radiator on the board. When the load current needs to exceed 1A, the rectifier bridge and output tube need to be installed with large heat sinks. It is recommended that they can be fixed at the bottom of the chassis for heat dissipation. Remember to add thermal silica and insulating sheets.Input voltage requirements:Generally, the voltage difference after rectification of the input voltage should be 4~6V higher than the output voltage.[Calculation formula: input AC*1.414-output DC= 4-6V]The relationship between the output DC voltage and the secondary AC voltage of the transformer is as follows:Output: when 5VDC, the transformer selects 9VACOutput: when 9VDC, the transformer selects 12VACOutput: when 12VDC, the transformer selects 15VACOutput: when 15VDC, the transformer selects 18VACOutput: when 18VDC, the transformer chooses 20VACOutput: when 24VDC, the transformer selects 24VACSpecifications:Dimensions: 100mm*70mm*1.6mm Height：42mmPCB process: FR4 military grade, 1OZ copper.Use Nichicon capacitance and wima Precautions:Due to consideration that customers may need to be fixed on the chassis bottom to dissipate heat, neither the kit nor the finished board is equipped with a radiator.The component parameters of the kit and the finished board are the configuration of output DC12V. The potentiometer is used with 20K VR, and the corresponding adjustable output voltage range is DC 3.2V~15V. If you need to output a higher voltage, you need to adjust the board. For filter electrolysis withstand voltage and fine-tuning potentiometer parameters, please consult customer service for details.Note：Diy Kit：all parts need buyer to solder it ！Assembled Board：have solder it well ！
