 LED display The power as an important part to provide power supply system, choose a qualified and reliable power supply, right LED Display energy saving effect and service life are all has obvious improvement effect, so how to correctly identify and choose a qualified LEDDisplay power supply?Strong color giant recommendation can be from the following7Aspects to consider:

      First, look at process to select the appearance LED Display power supply.A good power supply manufacturer, its working process is very strict, because in this way can we ensure batch consistency of the product.An irresponsible manufacturers, the production of power its appearance, tin, the arrangement of components uniformity will never good.

    In the second place, from full load efficiency LED Display power supply.The efficiency of the power supply is one of the most important indicators, high efficiency of power energy conversion rate is high, this not only conforms to the requirements of energy conservation and environmental protection, can real help users to save electricity saving again.

    Third, constant voltage power supply output voltage ripple.The size of the ripple has very big effect on the service life of electric equipment, ripple as small as possible.

    Fourth, observe the rise of temperature of the power supply work to choose LED Display power supply.Temperature affect the stability of the power supply and life, the temperature rise of the temperature is lower, the better.Also see from the aspects of efficiency, average heat efficiency will be small.

   Fifth, Due to theLEDDisplay properties of the products, when playing video or pictures will usually produce instant change of current, that's rightLEDThe power supply more strict requirements are put forward.Usually, in order to ensure the normal order of the display screen, need a certain amount of allowance for power supply products.The more general sense, surplus reserve, product performance more stable power supply, the longer the life span, however, thereby increasing the cost of power supply products, too much surplus reserve also easy to cause waste.At present, the industry's LED Display power are generally reserved20% - 30%The allowance.


     Sixth, in order to make the life of the power supply growth, suggested to choose more30%Rated output power.For example, if the system needs to be one100WThe power supply, selected is greater than is recommended130WThe rated power output model, and so on can effectively improve the service life of power supply.


   Seventh, according to the application field to select the function of the power supply, such as protection function: over voltage protection, over temperature protection, over load protection etc.Application functions: signal function, remote control, telemetry, parallel functions, etc.; Special features: power factor correction (PFC), constant electric (UPS)。
