Description

The aim of F1 is to bring the most real, pure and intact voice to audience.

​To fulfil all Hi-Fi requirements on stable power source and multiple output connector type, Silent Angel perfectly adds multiple technologies, such as high-efficiency toroidal transformer, advanced fully symmetric circuit design, low noise MOSFET in parallel and EMI filter.

​With stable electricity input to ensure the consistency and integrity of your musical enjoyment.

The LAN port on the Hi-Fi brings new challenge to power supply.

​To playback digital music or high resolution music, network player needs to handle about 200MB – 1GB data for DSD format music in 5 minutes.

​The working frequency is at least 1,000 times that a normal linear power supply can handle.

​F1 is the solution to high frequency nature of network for 5V powered network devices (such as: Bonn N8), network audio player, Raspberry Pi board, etc.

Toroidal-symmetric Transformer

The improvement of efficiency is obvious.

In addition, the energy-saving superiority of toroidal design is that the no-load current is merely 10% compared with a laminated one.

Advanced Full Symmetric Circuit

A distinct advantage of F1.

This design can eliminate most of the internal noise, the symmetric circuit is able to consolidate the accuracy of power output and ensure a stable power supply.

Low Noise MOSFET Parallelled

MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a vital component for F1 to control voltage output.

As a MOSFET controls output by adjusting the gate voltage, its gate drive circuit is less complex than BJT’s base drive circuit.

As a result of less complex design, the switching frequency of a MOSFET is higher than BJT’s, which supports a more precise and stable voltage output.

Effective Protection Mechanism

Adopting an output voltage detection circuit, an output current protection circuit.

Two temperature controlled protection circuits to cut the output. Preventing damage to your connected devices with unexpected power failures.

Output Connectors

F1 has two pairs of connectors, which consists of one USB and one DC sockets, and there are two 60cm x 5.5mm x 2.1mm DC plug to 5.5mm x 2.1mm DC plug  in packing box to help users to connect F1 to other appliances.
