It can simultaneously power up to three devices thanks to two DC outputs and one USB-A output, making it a particularly practical solution for setups including a DAC, preamplifier, headphone amplifier, CD transport, or other compatible audio devices.\u003cbr\u003e\u003cbr\u003eAt the heart of the PSU20 is an 80W pure copper toroidal transformer, capable of delivering up to 100W peak power. This design ensures stable power even when multiple devices are connected simultaneously.\u003cbr\u003e\u003cbr\u003eTo minimize electrical noise that can affect sensitive audio equipment, Fosi Audio uses Nippon Chemi-Con capacitors and an architecture that achieves extremely low ripple, down to 0.1 mV. The three outputs are fully isolated from each other and each have their own rectification, filtering, regulation, and protection circuits. This design reduces interference between different connected devices.\u003cbr\u003e\u003cbr\u003eThe PSU20 offers excellent flexibility with its selectable output voltages. The first DC output provides 12V or 15V with a maximum rated power of 20W, while the second DC output provides 12V or 5V up to 15W. An additional USB-A output delivers 5V \/ 1A, up to 5W.\u003cbr\u003e\u003cbr\u003eSafety and reliability are also central to the design. The PSU20 integrates protections against overheating, overvoltage, and overcurrent. A silent fan activates when the temperature reaches 55°C and operates at only approximately 30 dB to maintain a quiet listening environment.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMain Features:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eHigh-quality linear power supply designed for Hi-Fi audio systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCan simultaneously power up to three devices\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTwo DC outputs and one USB-A output\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFully isolated outputs to reduce interference between devices\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e80W pure copper toroidal transformer with peak power up to 100W\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUltra-low ripple down to 0.1 mV for clean and stable power\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHigh-quality Nippon Chemi-Con capacitors\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSelectable DC output 1: 12V \/ 15V, rated power 20W\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSelectable DC output 2: 12V \/ 5V, rated power 15W\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUSB-A output: 5V \/ 1A, rated power 5W\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSelectable AC input 115V \/ 230V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCompatible with DACs, CD transports, headphone amplifiers, preamplifiers, and other compatible audio devices\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOverheat, overvoltage, and overcurrent protections\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSilent fan automatically activated at 55°C\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOperating temperature from -20°C to 40°C\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePackage Contents:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1x Fosi Audio PSU20\u003c\/li\u003e\n\u003cli\u003e1x DC-DC power cable 1.2 m\u003c\/li\u003e\n\u003cli\u003e1x DC-DC power cable 0.3 m\u003c\/li\u003e\n\u003cli\u003e1x AC power cord\u003c\/li\u003e\n\u003cli\u003e1x User manual\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fosi Audio","offers":[{"title":"Default Title","offer_id":54917503779155,"sku":"FA-PSU20","price":239.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/7414\/8691\/files\/01_892c255c-0c52-4207-8759-6b4cbc776c38.jpg?v=1789132790","url":"https:\/\/urban-tech.be\/en\/products\/fosi-audio-psu20-alimentation-lineaire-hi-fi-5v-12v-15v-3-sorties","provider":"Urban-Tech","version":"1.0","type":"link"}
