Finished Board Linear Power Supply High Current Stabilized Power Supply Board with Low Noise and 1 - 10A Tube for Toshiba
Description:
- Note that the recommended working current is 1A without heat sink. If you need to work with high current, remember to install a heat sink and the thermal silica gel.
- The benchmark of this kit is LM317 for ST, using output tube king 1943, the output linearity is very good at high current, the frequency band is also wider than LT1083, so it is very suitable for HIFI power supply, and it can also be used as laptop power supply. The output also adds CLC 2 level filtering, whose high frequency is more pure.
- Because of the large current, the linear power supply heats up more than the switching power supply, but the ripple is much lower.
- Pay attention to one point. The rectified voltage after input must be 4V higher than the output. For example, if you output 12V, the minimum input rectified voltage should be 16V. But it's not that the greater the pressure difference, the better. The greater the pressure difference, the greater the heat generation.
Specification:
- Board size: 100 x 88mm
- Input voltage: AC6V-AC33V
- Output voltage: DC33V-DC37V
Package Included:
- 1 x Power Supply Board
