Why choose F1 Linear Power?

Silent Angel F1 is a reliable linear power supply tailored for N8 and Raspberry Pie 4 Model B. The aim of F1 is to bring the most real, pure and intact voice to customers. Zero noise, zero data corruption and zero power break-off, F1 is like a true forester to guide you to feel the touch of winds, step into sunshine and hear the slight friction sound of leaves. Not matter wave’s lapping or rabbits’ whispers, all sounds can be distinguished by your ears with F1’s supporting. To fulfill all Hi-Fi requirements on stable power source and multiple output connector type, Silent Angel perfectly add multiple technologies into F1, which includes: high-efficiency toroidal transformer, advanced fully symmetric circuit design, low noise MOSFET in parallel and EMI filter. It is not only a power supply, but also a guardian for the music journey. Compared with cheaper power supply, F1 has a more stable electricity input to ensure the consistency and integrity of the music enjoyment. Reference to running test, ONE F1 can easily provide continuous and pure power to TWO N8 simultaneously.

Optimal materials to ensure machine quality

To present the originality of Silent Angel, the shell of F1 consists of high-quality-thick material to reduce vibration of transformer. The panel adopts CNC progressing to ensure congruence. Addtionally, the surface adopts drawing progress to make the shell more pretty.

High-efficiency Toroidal-symmetric Transformer

The toroidal design approximately halves the occupied space and the weight of transformer comparing with the laminated design at the same degree. The improvement of efficiency is more obvious as well. The core permeability of toroidal design is higher than the laminated, which conduce to the electrical efficiency of transformer trend better consequently. In addition, the energy-saving superiority of toroidal design is that the no-load current is merely 10% comparing with the laminated.

Advanced Full Symmetric Circuit

A distinct advantage of F1 is fully symmetric circuit design. This design can eliminate noise inside F1 utmostly. The symmetric circuit is able to consolidate the accuracy of power output and ensure a stable power supplying likewise.

Low Noise MOSFET in Parallel

Like sluice gate to water flow rate, MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a vital component for F1 to control voltage output. Usually, low power appliance prefers to choose BJT (Bipolar Junction Transistor) as its output voltage controller. However, F1 pursues the best user experience so that MOSFET is chosen. There are multiple preponderances of MOSFET. As 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 MOSFET is higher than BJT’s, which supports a more precise and stable voltage output.

Multiple types of output-connector

As tailored for N8 and Raspberry Pie 4 Model B, F1 covers two pairs of connectors, which consists of one USB and one DC plugs. Moreover, there are TWO 60 cm 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 the appliances they would like to use.

Because of the characteristic of symmetric design in F1 circuit and transformer. F1 has the best performance while being connected to two similar loading. Such as: two N8. Above figure shows the best way to use one F1 and two N8.
