How to choose power supply for your LED Mesh Screen?

As an important part, LED Mesh display power Supply  provide power  system, choose a qualified and reliable power  supply, energy saving effect of LED Mesh Screen and service life are obvious promotion effect, so how to correctly identify and choose a qualified LED Mesh display power supply?

Here are seven things to consider:

First, look at the appearance process to select the LED Mesh display power Supply. A good power Supply supplier, it is also very strict to the working process, because this can guarantee the batch consistency of the product. An irresponsible manufacturer, the production of the power Supply of its appearance, tin, the arrangement of the elements is absolutely not good.

Second, choose LED Transparent display power   supply from full load efficiency. The efficiency of the power supply is the most important index, the efficiency is high power conversion rate is high, so that it is attached to the requirements of energy conservation and environmental protection, and can actually save the electricity for users.

Thirdly, the output voltage ripple of constant voltage power supply is large. The size of the ripple effect has a very large effect on the life of the electrical equipment. The smaller the ripple, the better.

Fourth, observe the increase of the temperature of the power  supply to select the power of LED Mesh Screen. The increase of temperature affects the stability and life of the power supply. The lower the temperature, the better. In addition, it can be seen from the efficiency that the general efficiency of high temperature will be small.

Fifth, because of the properties of LED Transparent display products, the current of instantaneous change will usually be generated when playing video or screen, which puts forward more stringent requirements on LED power supply. Usually, in order to ensure the normal broadcast of the display screen, you need to reserve a certain amount of allowance for the power supply. 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. Currently, the power Supply supply of LED Mesh display screens in the industry is usually reserved by 20% – 30%.

In order to increase the life span of the power  supply, it is recommended to choose a machine with a power  rating of 30%. For example, if the system needs a 100W power  supply, it is recommended to select a model with a power Supply rating of more than 150W, which can effectively improve the life of the power  supply.

Seventh, select the power supply according to the application field.

Protection function: over voltage protection, temperature protection, over-load protection, etc.

Application function: signal function, remote control function, telemetry function, parallel function, etc.

Special function: work correction (PFC), continuous electricity (UPS).
