Core Key Features

• Triple O-Core Transformer Pure Power System
  Built with 1×250W + 2×120W high-permeability O-core transformers, adopting premium 0.23 silicon steel sheet integral craftsmanship. This low-loss, low electromagnetic interference power core delivers massive power reserve, ensuring stable, distortion-free continuous power output even under full multi-device load, effectively eliminating power compression that degrades Hi-Fi sound quality.
• 3 Groups of Independent Isolated Outputs with Adjustable Voltage
  Fully isolated multi-channel design completely cuts off electrical crosstalk between different audio devices, covering all mainstream Hi-Fi equipment scenarios:
  ✅ Output 3 (12V–23.5V adjustable / 7.5A): For high-power Roon servers, NAS, audio mainframes and high-demand streaming devices
  ✅ Output 2 (9V–13.5V adjustable + 5V fixed, max 15V customizable / 4.5A): For Hi-Fi DACs, music streamers and USB audio interfaces
  ✅ Output 1 (9V–13.5V adjustable + 5V fixed / 4.5A): For audio network switches, Raspberry Pi and Roon audio bridges
• Industry-Leading 86µV RMS Ultra-Low Ripple Noise
  Professionally tested and certified by Tektronix oscilloscopes, the output ripple noise remains as low as 86µV RMS under 4.5A full-load conditions. Far quieter than ordinary linear power supplies and switching power adapters, it thoroughly filters mains grid clutter and high-frequency noise, delivering pure, clean power for smoother vocal performance, richer instrumental timbre and accurate sound field positioning.
• High-Speed USB Isolator + USA Crystek Femto Second Clock
  Equipped with a built-in USB 2.0 high-speed isolation module, this unit completely eliminates ground loop noise and USB bus digital interference. Paired with original US made Crystek femto-second precision clock, it drastically reduces audio jitter, optimizes digital audio transmission fidelity, and restores authentic, delicate high-resolution audio details.
• Global Wide Voltage & 24/7 Long-Term Stable Operation
  Supports switchable 110V–120V / 220V–240V input voltage for global worldwide use. The heavy-duty 14KG full-aluminum alloy chassis suppresses mechanical vibration and electromagnetic radiation. Dual oversized side heat sinks provide efficient heat dissipation, over current protection, enabling 24/7 non-stop stable operation with zero performance attenuation, perfect for long-running home audio systems.

Standard Package Contents

• 1 × Standard Power Cord
• 2 × 1m DC 5525/5521 Barrel Plug Power Cables
• 1 × 1.5m Type-C 5V USB Power Cable

Custom-length & custom-plug power cables are available via customer service consultation for personalized Hi-Fi device matching.
