How to judge the security of LED display?

When we use LED display, equipment safety is a very critical issue, in order to let you can buy assured products, here let us look at several aspects of judging the security of LED display.

Judging the security of LED digital display screen from the following aspects：

1. Power switch: the power switch must be able to meet the actual use of the rated power, to avoid the actual use of the load exceeds the rated power of the power switch, resulting in excessive load of the power switch, causing the power switch to burn out, causing fire.

2. Selection of LED display screen: don't think that the pursuit of bright effect, easy to lead to device aging, reduce service life, and easy to aging fire.

3. Kit: whether the material has passed the fire retardant requirements of UL94V0 standard.

4. Whether the wire is international wire, whether it has passed the fire resistance requirements of IEC60332 standard, and whether the size of the wire core has left sufficient margin in actual use.

5. Power supply line: know whether the distribution of module power supply is balanced in dc power supply line, whether the multi-channel output of ac power supply line is balanced, and whether the daily output power is balanced, so as to reduce the probability of fire caused by the line.

6. Key components: heating key components can be maintained at a reasonable temperature for a long time.

These are the aspects that affect its safety. I hope you can pay attention to the above knowledge when making your choice.
