Power supply is very important for the sensitive device, such as Digital-to-Analog DAC or USB SPDIF converter,digital device. phono preamp etc.,even though power by USB or switch power adapter is convenient and high efficient,but higher ripple and noise than linear power supply solution.

This stable linear power supply helps you to resolve problems and upgrade your device working performance!
Sound quality will more clearly,sound background is more quietly.

Quality components:
25VA Bingzi transformer
low-noise voltage regulator circuit+high speed op amp+MOS output transistor
aluminium chassis for better heat dissipation
hifi electrolytic capacitors
multistage of precision big current filter inductor
LED voltage display on front
trimmer potentiometer to adjust voltage on rear
(adjust range within 0.5V,because different voltage needs different transformer and resistor. this device is DC5V only.)

Specification:
Input voltage: AC 110V
Output voltage: DC 5V / max 3.5A
(max current 3.5A for total 2 sockets together)

(Note: Please check DC voltage and current requirement, and DC port size of your device firstly.)

Packaging List:
1 x AC power cord(US standard plug)
1 x DC cable (terminal 5.5*2.5mm, inside+,outside -)
1 x convertor of micro usb for pi3)

(Note:if you connect with 2 devices at the same time,please check if their total current requirement more than our 3.5A or not.
the power supply can not working overload)

If any questions, you can email us.

Note:
(1) cause temperature,external power supply and display accuracy limit, error 1-2% on display module is normal when power no-load for example, 5V but display 5.2V, it is normal.
(2) load error 5% is normal
