New breakthrough in LED power supply - How does Maimi Electric break the

Driven by the wave of digitalization and intelligence, LED displays have been widely used in outdoor advertising, traffic instructions, stage performances, sports venues and other scenarios. With the continued growth of the domestic market and the rapid expansion of overseas demand, the industry's comprehensive requirements for display effects, stability and energy efficiency are also continuing to increase. Power supply system, as the core link that supports the stable operation of display equipment, is facing unprecedented technical challenges.

As LED displays evolve towards higher brightness, lower power consumption and larger sizes, higher requirements are placed on the adaptability and performance level of the power supply system. Traditional power supplies commonly have problems such as low load and low efficiency, low power factor (PF), and poor grid adaptability. Especially in remote areas or countries and regions with frequent grid fluctuations, they are more likely to cause unstable screen operation and shortened system life, which have become key shortcomings restricting the high-quality development of the industry.

Maimi Electric’s high-efficiency solution for LED power supply in all working conditions

Shenzhen Megmeet Electric Co., Ltd. (referred to as "Maimi Electric") commercially displays LED power supply as the national manufacturing individual champion.

Relying on the profound power electronics technology accumulation, focusing on the industry problem of "low voltage and low load", we launched a new generation of medium and high power LED power solutions. This product achieves systematic optimization in multiple dimensions such as power supply architecture, control strategy and device layout, effectively improving the efficiency and stability of the power supply under all working conditions.

This series of power supplies (taking 600W as an example) adopts a PFC+LLC two-stage architecture design, dual voltage output, and can be connected to a common cathode or a common anode. The PFC module uses continuous conduction mode Boost topology and supports AC90-264V full voltage range input. The PF value is stably maintained above 0.98, significantly improving the energy efficiency of the entire machine.

In addition, this series of power supplies hasIt also performs well under load scenarios. Under full load conditions, it can calmly cope with extreme situations such as power grid voltage fluctuations and surges, ensuring that the display continues to output stably and avoids frequent restarts. Under light load conditions, high efficiency and high PF value can still be maintained even at 10% low load condition. At the same time, it can also provide customers with output voltage programming function, which can dynamically adjust the voltage output state, perfectly adapting to energy-saving scenarios such as low-brightness operation, partial screen off or standby, and achieving dual optimization of energy consumption and performance.
