With six separate power zones, the P28 ranges from smaller 5 V components to more power-hungry equipment requiring up to 10 A. This makes it particularly interesting in a larger digital setup with, for example, a streamer, DAC, music server, and network equipment. Inside, a toroidal transformer works together with separate grounding connections and an analog circuit design without ICs. The P28 does not add new streaming functions or more formats to your system – its task is more fundamental: to give the components you have already chosen a stable, low-noise power supply to work with.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eHighlights\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eLinear DC power supply\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSix separate power zones\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eZone I: 5 \/ 7 \/ 9 \/ 12 V – up to 4 A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eZone II: 12 \/ 15 \/ 19 \/ 24 V – up to 4 A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eZone III: 12 \/ 15 \/ 19 \/ 24 V – up to 6 A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eZone IV: 12 \/ 15 V – up to 10 A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eZone V: 5 \/ 9 V – up to 2 A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eZone VI: USB 5 V – up to 2 A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eToroidal transformer\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSeparate ground for each output\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAnalog circuit design without ICs\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRipple noise below 100 µV at full load\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIntegrated USB isolator\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eKECES Quantum Resonance Technology\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAluminum cabinet\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eKECES' own audio-grade feet\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eSix zones make room for an entire system\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eWhat we especially think makes the KECES P28 interesting is the range across the six separate outputs. The different zones are not just copies of each other, but cover different voltages and power requirements. The most powerful can deliver up to 10 A at 12 or 15 volts, while other zones can take care of less demanding components. This makes it possible to gather several parts of the digital system around one linear power supply instead of having a separate solution for every single unit. And because each zone is separate, components with different requirements can be powered from the same cabinet. It is, of course, crucial to check voltage, power requirements, polarity, and connector type for each component before connection.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eWhen the power supply gets the same attention as the rest of the system\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eInside, the P28 uses a toroidal transformer, separate grounding connections for each output, and an analog circuit design without ICs. KECES specifies ripple noise at below 100 µV at full load and below 10 µV at 60% load. For us, this is exactly where the idea behind the P28 makes sense: when the streamer, DAC, and other hi-fi components have already been chosen with care, you can start looking at the electrical working conditions around them. The P28 is designed to deliver stable DC power with a low noise level, so the power supply affects the connected electronics as little as possible. KECES also uses its Quantum Resonance Technology, which the manufacturer describes as a technology developed with a view to better timing and cohesion between electromechanical components.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eMore than a large collection of DC outputs\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe sixth zone combines 5 V power with an integrated USB isolator, providing an extra option in digital hi-fi systems where the USB connection also needs to be considered. The construction is housed in an aluminum cabinet measuring 300 × 279 × 133 mm and weighs 14 kg. That also says a little about what kind of product the P28 is: it is not a small adapter to be hidden behind the system, but a true hi-fi component designed to stand together with the rest of the electronics. KECES has also equipped it with its own audio-grade feet and highlights the construction as low-noise, without hum at 50 Hz and peak load. If you have several compatible DC components and want one unified power platform for them, this is exactly where the P28 stands out from the smaller models in the KECES range.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eDid you know?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003e✓ You get 30 days of Buy \u0026amp; Try\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e✓ You get an extra year of warranty when you sign up for our newsletter\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e✓ You get free shipping over 499,-\u003c\/span\u003e\u003c\/p\u003e","brand":"Keces Audio","offers":[{"title":"Default Title","offer_id":55631618605432,"sku":"55631618605432","price":2888.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/6253\/3137\/files\/P28.png?v=1786710063","url":"https:\/\/www.lydspecialisten.eu\/products\/keces-p28","provider":" Lydspecialisten","version":"1.0","type":"link"}
