1，LED module the maximum voltage value must be less than the maximum output voltage of the power supply;
2，LED module rated current value must be greater than or equal to the rated current of the power supply;
3，Whatever the application, the ambient temperature of the power supply must be less than the rated maximum ambient temperature, the rational design of LED terminal equipment can maximize the life of the power
4，The power supply of the best efficiency value at 70% -100% load range, reasonable design LED module, to maximize the utilization of the power supply;
5，The power supply cannot be installed in flooded environment;
6，Outdoor applications cable connector must make good contact and prevent the oxidation;
7，The power supply is considered a component used in conjunction with the terminal equipment, EMC effect by the entire device, terminal equipment manufacturers are required to complete installation of EMC reconfirmation.
