KECES P28
Ultra Low Noise Regulated Linear Power Supply 6 Outputs 5 / 7 / 9 / 12 / 15 / 19 / 24V DC 28A
The Keces P28 is a high-quality regulated linear power supply. This power supply will provide your HiFi audio system with a clean electrical signal. The Keces P28 benefits from a totally analogue design and high-quality components such as a very powerful toroidal transformer. Each of the 6 output channels has a separate ground. The quality of this power supply’s design results in an ultra-low noise signal and eliminates any noise at 50Hz and at maximum load. For this P28 power supply, Keces has also chosen to use Quantum Resonance technology, which enables electromagnetic components to resonate in the same time to improve coherence and synchronization. It also incorporates OCP protection in the event of overcurrent and OTP protection in the event of overheating.
The KECES P28 power supply must be placed in a well-ventilated area. In addition, it must not be positioned above or below any other HiFi equipment.
USB isolator
In addition to these 5 power supply outputs, the Keces P28 has a USB isolator with a USB-B input and a USB-A output (5V 2A). This USB isolator will allow you to enjoy your digital signal sources such as a computer while protecting the signal from noise generated by the source device. The isolator supports PCM sampling rates up to 24bit 96kHz and DSD up to DSD64.
