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

Preface

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. As the core link that supports the stable operation of display equipment, the power supply system 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 accumulation of power electronics technology, 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 also performs well in different load scenarios. Under full load conditions, it can calmly cope with extreme situations such as grid voltage fluctuations and surges, ensuring continuous and stable output of the display and avoiding 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.

Multi-dimensional innovation from structure to algorithm

Maimi Electric has introduced high-reliability magnetic components and thermal management optimization design into this series of products, and optimized the layout of key components through thermal simulation analysis, effectively reducing the temperature rise of the entire machine and improving system stability and service life. At the same time, this series of products meets the requirements of multiple international certifications such as CE, UL, and CB, and can be widely adapted to market regulations in different countries and regions, helping customers accelerate global business expansion.

Maimi Electrical LED Power Supply Dialogue Global

From June 11th to 13th, Maimi Electric will bring its new LED power supply solution to the InfoComm exhibition in the United States (Booth: West Hall, Booth 4467). Through immersive experience and dynamic physical demonstrations, it fully demonstrates the strength of its power supply technology. The audience can personally experience the stable operation of this solution under extreme low voltage and ultra-light loads, and intuitively experience its excellent grid adaptability and energy-saving effect. In addition, on-site technical experts also conducted in-depth exchanges with customers around the world on the application needs of different regions.

The appearance at the InfoComm exhibition not only verified the ability of Maimi Electric's new LED power supply solution to overcome the core problems of the industry, but also provided solid technical support for the intelligent and green development of the global LED display industry with its highly integrated, super adaptable, intelligent and reliable innovative architecture!
