Feature

1. Three Fully Isolated Outputs, Zero Interference

The PSU20 features dual DC outputs plus one USB-A port, powering three devices simultaneously from a single source. Each channel has its own dedicated rectification, filtering, regulation, and protection circuitry, ensuring clean, stable delivery with no cross-talk between connected components.

2. 40W Rated Output with 100W Peak Headroom

Built around an 80W custom pure-copper toroidal transformer, the PSU20 delivers 40W continuous power and up to 100W peak output. Even with three devices drawing full load, it maintains rock-solid stability for demanding musical passages.

3. Ultra-Low 0.1mV Ripple for a Blacker Background

Premium Nippon Chemi-Con capacitors combined with a Texas Instruments quad-core linear regulation design reduce ripple to just 0.1mV. The result is a simpler, more controllable noise spectrum than switching supplies, unveiling a darker background and more revealing detail.

4. Intelligent Thermal Management for Long-Haul Sessions

A custom low-noise cooling fan activates automatically at 55°C and runs at only 30dB. Combined with over-temperature, over-voltage, and over-current protection, the PSU20 stays cool and stable through extended listening while safeguarding your gear.

5. Flexible Voltage Selection, Broad Compatibility

DC1 toggles between 12V and 15V, DC2 between 12V and 5V, while USB delivers 5V/1A. Whether you're running a DAC, headphone amp, or streamer, one PSU20 covers the complete power needs of your desktop audio system.
