LED display power supply as an important part of the power supply system, select a qualified and reliable power supply, LED display energy saving effect and service life are significantly improved, then how to correctly identify and select a qualified LED display Power it? Strong Ju Cai recommended can be considered from the following seven aspects:
First, look at the appearance of technology to choose LED display power. A good power supply manufacturers, its workmanship is also very strict, because in order to protect the bulk of the product consistency. An irresponsible manufacturer, the production of power its appearance, tin, the arrangement of components will not be good. Second, from the full load efficiency to choose LED display power. The efficiency of the power supply is the most important indicator. The energy efficient conversion rate is high, which not only meets the requirements of energy saving and environmental protection, but also realizes power saving and saving for users.
Third, the constant voltage power supply output voltage ripple. The size of ripple has a very big impact on the life of electrical equipment, the smaller the ripple as possible.
Fourth, observe the power supply temperature rise to choose LED display power. Temperature rise affects power supply stability and life expectancy, the lower the temperature rise the better the temperature rise. In addition, it can be seen from the efficiency, the general efficiency of high temperature rise will be small.
