{"product_id":"kecesp28","title":"KECES P28 Linear Power Supply","description":"\u003cp\u003eThe KECES P28 is the brand's linear power supply flagship: a purely analogue multi-zone power supply that feeds up to six audio devices simultaneously with clean power – each zone fully isolated and with its own earth.\u003c\/p\u003e\n\u003cp\u003eWhere smaller power supplies feed two to four devices, the P28 covers a complete, multi-part digital and pre-amp chain. Supplied as a single unit with a DC cable set and mains cable.\u003c\/p\u003e\n\u003ch2\u003eWhy the KECES P28?\u003c\/h2\u003e\n\u003cp\u003eBecause with large chains, power is the foundation. Six separate zones with their own earth stop one device from disturbing another; the discrete circuitry does without integrated chips, and a massive toroidal transformer delivers hum-free energy even under load. The built-in USB isolator keeps computer interference away from the DAC.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eAn uncompromising power hub with plenty of reserve: ripple stays below 10 µV under normal load, and Zone IV delivers a full 10 A – enough to feed even power-hungry music servers or small amplifiers. The separate earth per zone also clears up ground loops.\u003c\/p\u003e\n\u003ch3\u003eWho is the P28 suited for – and who isn't it for?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePlain talk:\u003c\/strong\u003e the P28 is meant for large, multi-part high-end chains that want many devices cleanly powered. For a lean streamer-DAC combo, it's simply too much of a good thing – the P6, P9 or P14 are enough there. At 14 kg and 133 mm tall, it needs full rack space and a bit of room to breathe.\u003c\/p\u003e\n\u003ch3\u003eWhat does \"discrete circuit design without ICs\" mean?\u003c\/h3\u003e\n\u003cp\u003eKECES builds the circuit from individual, high-quality components instead of standard chips. That's more elaborate but allows more precise control over noise and sonic behaviour.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe power flagship for perfectionists: six isolated zones, plenty of reserve, USB isolator, very low noise. If you want to power a large chain from a single source, this is as far as it goes. At HD Zürisee in Wädenswil, we plan the zone allocation for your devices.\u003c\/p\u003e\n\u003ch2\u003eTechnical Data – KECES P28\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: linear six-zone power supply with USB isolator (purely analogue, no ICs)\u003c\/li\u003e\n\u003cli\u003eZone I: 5 \/ 7 \/ 9 \/ 12 V, 4 A\u003c\/li\u003e\n\u003cli\u003eZone II: 12 \/ 15 \/ 19 \/ 24 V, 4 A\u003c\/li\u003e\n\u003cli\u003eZone III: 12 \/ 15 \/ 19 \/ 24 V, 6 A\u003c\/li\u003e\n\u003cli\u003eZone IV: 12 \/ 15 V, 10 A\u003c\/li\u003e\n\u003cli\u003eZone V: 5 \/ 9 V, 2 A\u003c\/li\u003e\n\u003cli\u003eZone VI: USB 5 V, 2 A (with isolator)\u003c\/li\u003e\n\u003cli\u003eUSB isolator: PCM up to 24-bit\/96 kHz, DSD64\u003c\/li\u003e\n\u003cli\u003eRipple: below 100 µV at full load (below 10 µV at 60 % load)\u003c\/li\u003e\n\u003cli\u003eEarthing: separate ground per zone\u003c\/li\u003e\n\u003cli\u003eHousing: aluminium, 4 mm wall thickness\u003c\/li\u003e\n\u003cli\u003eDimensions (W×D×H): 300 × 279 × 133 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 14 kg\u003c\/li\u003e\n\u003cli\u003eIncluded: P28, DC cable set, mains cable, manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eHow many devices can the P28 power?\u003c\/h3\u003e\n\u003cp\u003eUp to six at once: five DC zones with selectable voltage and current up to 10 A plus a USB zone with isolator.
