This low-noise linear power supply is ideal for audio equipment and network devices up to 50VA. I purchased it on AliExpress and stored it in a dark place, but it's no longer needed due to a system change. I checked the power-on and output voltage for the photos, but I haven't used it with any equipment. The product features and specifications are shown in the images, so please refer to them. Regarding the product's condition, including the included DC cable, there are some minor scratches and scuffs that were present from the beginning, but there are no noticeable scratches. The room is dry, so dust on the product may be more noticeable than in the summer. The listed product is DC 12V, but unlike other products, you can significantly adjust the output voltage using the trimmer on the board (the blue component with the minus knob). With another unit I purchased at the same time, I was able to adjust the voltage between DC 3.17V and DC 17.40V. It operates stably with a Laiv Audio Harmony μDAC at DC 15V 2A. The listed product showed DC 12.137V on a tester in an AC 103.4V environment. This product has obtained the FCC mark (USA) and CE mark (Europe), which are safety standards for electrical products, but it does not have the PSE mark because it is not sold in Japan. The quality of the parts and the build are good, and the operation is stable, but if you are concerned, please refrain from purchasing. I do not smoke. I do not have any pets. Thank you.
