Problems solved by technology

However, the above-mentioned power meters still have certain disadvantages in actual use. In order to prevent fine particles such as dust in the external environment from entering the inside of the power meter, some power meters adopt a fully enclosed shell structure, and assist heat dissipation through cooling fins and other components. In areas with high temperature, power meters often overheat, and, affected by this, the incidence of internal component failures increases significantly, affecting the use of
