Fosi Audio PSU20 Linear Power Supply

Power Three Devices Simultaneously
With dual DC outputs and one USB-A output, the PSU20 can power up to three audio devices from a single source.

Flexible Compatibility
Supports selectable 5V, 12V, and 15V outputs, making the PSU20 compatible with CD transports, DACs, headphone amplifiers, and preamps.

3 Fully Isolated Outputs
Each output has its own dedicated rectification, filtering, regulation, and protection circuitry to deliver clean, stable power without interference between connected devices.

0.1mV Ultra-Low Ripple
With ripple as low as 0.1mV, the PSU20 helps reduce ripple noise and deliver a cleaner background for high-fidelity audio systems.

Engineered for Stable Long-Term Use
A custom low-noise fan activates at 55°C and operates at just 30dB, while over-temperature, over-voltage, and over-current protection help safeguard connected audio equipment.
