A11 Ultra Low Noise Linear Power Supply Board Base On Sigma11 (With heatsink)




The latest fully discrete ultra-low noise linear power board in 2021. highly recommend use for updates Upgrade Raspberry Pi / DAC / Preamp / headphone amp / Router etc switching power supply. 
You will can hear a great improvement in sound quality.

PCB Size: 180mm*45mm   
Heatsink Size: 245mm*60mm*25mm 
With this heatsink. the board can output max about 5A current.

Height:when output voltage<=18V. the one main Filter capacitor are using 4700uf/35V. as photo show.
             the height is about 40mm.  with heatsink is about 65mm

            when output >18V. the one main Filter capacitor are using 1000uf/50V. also nichicon KG Type I
             the height is about 55mm.  with heatsink is about 80mm


Output voltage:   we can make DC3.3V-32V  all kinds voltage.  if you needs voltage is not include in this list. you can choose "custom voltage"Options. then add a paypal note or send a message to us after paid it.


Output currect:  this board  can output max 6A.  when Continuous high current output. you need add a enough big heatsink.  this list default heatsink suitable for Continuous <=5A


If you choose"with heasink". we will installed the board to heatsink before shipping out.

Following is the Common output voltage recommended input AC voltage.

DC3.3V   recommend input AC5-6V
DC5V      Recommend input AC12V
DC9V      Recommned input AC15V
DC12V    Recommend input AC18V
DC15V    Recommend input AC20V
DC18V    Recommend input AC22V
DC19V    Recommend input AC23V
DC24V    Recommendd input AC28V
DC28V    Recommend input AC30V
DC32V    recommend input AC33V

Note: The input voltage allow appropriate error.

We can provide scheamtic for this board.
