Fosi Audio Remote Control For DA2120A/C Bluetooth Dac Amp

Lower Noise. Blacker Background.

Unlike switching power supplies, the PSU20 produces a simpler, more controllable noise spectrum. Combining premium Nippon Chemi-Con capacitors with a Texas Instruments quad-core linear regulation design, it reduces ripple noise and delivers a cleaner background for high-fidelity audio systems.

Power Three Devices Simultaneously

With dual DC outputs and a USB-A output, the PSU20 can power your entire audio system from a single source. Included DC-to-DC cables eliminate bulky power adapters and messy wiring, simplifying your setup and reducing cable clutter.

Fully Isolated Outputs

Each output features its own dedicated rectification, filtering, regulation, and protection circuitry, ensuring clean, stable power delivery without interference between connected devices.

Simplify Connection

Simplify your power adapter in one step, easier and neater cable management.

Perfect Match for Fosi Gear

Purpose-built for Fosi Audio components, the PSU20 offers seamless compatibility and a unified design that fits naturally into your system.

Smart Cooling. Ultra Quiet.

A custom low-noise cooling fan automatically activates at 55°C, operating at just 30dB. Efficient thermal management keeps the PSU20 running cool and stable during extended listening sessions.

Multiple Protections

Supports over-temperature, over-voltage, and over-current protection to safeguard your connected audio equipment and ensure reliable system operation.

80W Toroidal Transformer

Custom pure copper toroidal transformer with up to 100W peak output ensures stable power delivery, even with three devices connected.

Nippon Chemi-Con Capacitors

Premium capacitors help minimize ripple and noise, with ripple as low as 0.1mV.

High-Reliability Rectifier

A GBU806 rectifier bridge rated at 600V/8A ensures fast, stable AC-to-DC power conversion.

4-Core Regulation

Powered by three LM1085IT and one ST78M05 linear regulators from Texas Instruments.
