In residential areas, the buzzing of power electrical ready boards often becomes an "invisible killer" that damages the environment. The low-noise electrical ready board, through systematic acoustic optimization, controls the operating noise below 35 decibels, equivalent to a whisper level quiet experience.

The core breakthrough lies in the three-layer noise reduction system: firstly, a "sandwich" composite design is adopted in the box structure, which is combined with honeycomb shaped guide holes to form the Helmholtz resonance cavity effect, effectively absorbing mid to high frequency noise. Secondly, the "sound source isolation" strategy is adopted in the layout of components, which achieves physical isolation through rubber shock absorbers to block the vibration transmission path.

The innovation of the cooling system is equally crucial. At 30% load, the noise is only 28 decibels. By optimizing the heat dissipation hole array through thermal simulation, the airflow disturbance noise is reduced by 40% while maintaining heat dissipation efficiency.

This silent design not only meets the IEC60529 protection standard, but also has been validated through ANSYS acoustic simulation.
