This is the ON LM317 benchmark suite, with a gold seal output tube Wang MJL15025 output, high current output linearity is very good, the band also wider than LT1083, very suitable for HIFI power supply, also can do the laptop power supply, output plus 2 CLC high frequency filter, more pure. In the high current output as steady as Mount Tai
The product is their own form of welding parts, the welding processing cost generation need to take 15 yuan.
PCB is double-sided gold-plated, very high-end
Board size: 100X88MM
Input voltage: AC6V-AC33V, output voltage: DC 3V3-DC37V
Because the heat dissipation of the board is limited, the maximum output current of the sealing tube is exceeded by 5A, and the output pipe is replaced by Toshiba&39;s 2SA1943, and the heat dissipation is added to the 5A.
Because the current is large, the linear power supply is larger than the switching power supply, but the ripple is much lower, and the sound quality is too
Material is very in place, NOVER, 10000UF, gold, capacitors, Panasonic, FC back, even gold sealed tube 15024, etc., wheel tube rectifier, the United States BI adjustable resistor. If it doesn&39;t burn enough, you can use KG and KZ capacitors
Note 1 points, the input rectifier voltage is higher than the output of more than 4V, the effect is good, for example, you output 12V as input rectifier after the minimum voltage, but also 16V, but not the greater the pressure difference, the pressure difference, large heat.
