## Overview

The 25VA DC 5V Linear Power Supply is a high-performance desktop power adapter designed specifically for Raspberry Pi 3 models. With a maximum output of 3.5A and ultra-low noise operation, it ensures stable performance without disturbing sensitive audio devices. Its compact aluminum design makes it a perfect fit for any professional workspace.

## Description

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

Review: Quiet, stable - Used to power an RPI streamer setup. Quiet, no hum while powering my DAC. Stable enough for my purposes. Very well made, working like a charm for months now. Never gets above 120F. I couldn't be happier and the price is nice compared to alternatives.
Review: Good and Bad - Unit seems very good. Voltage adjustment worked great and unit holds its voltage well. I have not had to re-adjust since I set it. I an using it to power 2 FMC’s for fiber optic cable extension. Sound quality much better compared to the stock wall plugs. 2 issues I have experienced are the plug size for the DC input plugs are 5.5x2.5 NOT 2.1 as listed and the AC cord included is poor quality. The loose female plug end continuously disconnects. I upgraded to a better quality power cord and it works fine.

### ⭐⭐⭐⭐⭐ Works great for my Raspberry Pi
*by A***T on July 28, 2020*

Excellent product support as well! The seller gets back to you very fast. I purchased two of them. Disassembled the top lid and the internals are very nice. Phillips and UCC electrolytic capacitors in mine, not sure about the film caps. Look like Kemet. Nice transformer. Using this with a Raspberry Pie 3 and 4. Both have a HiFiBerry DAC + pro. Previously I was using a few different basic switch power supplies as well as a battery pack. This made a nice difference! Very happy with it. Amazon item B07MPS3QD8 worked well to let me terminate the 5.5mm x 2.1mm end connector to another cable. As stated the voltage reading on the front of the unit is inaccurate but big deal, the voltage when connected to a meter rests perfectly. I was easily able to dial up the voltage to 5.1v DC which is what the Raspberry Pi likes. No low voltage warnings when running RetroPie either!
