What LED power supply should be protective ability

One, the lightning protection ability
 
Outdoor lightning climate of great harm to the power supply, usually with direct lightning, thunder, lightning several types, such as the induction lightning is most common, is also the biggest damage to power supply, tend to produce 4 kv or higher voltage. Good power supply should have good lightning protection, and follow the national related design standard (GB/T 17626.5, the standard equivalent IEC - 61000-4-5, anti pressure differential mode 2 kv, common-mode compressive 4 kv). , of course, in addition to the one-piece power lightning protection design, some special lightning concentration areas, lighting users also can consult iec61643-1 or EN61643-11 related standards, such as in lighting lamps and lanterns transmission front independent lightning protection device, added effect will be better.
 
Second, the ability to resist high temperature to cold
 
In some areas outside the temperature can be as high as 50 ℃, and the lowest is often low to minus 30 ℃, this will require power supply must have a wider range of working temperature ring, in 40 ℃ to + 70 ℃ in the wide scope of work, guarantee the products reliable, stable performance.
Three, waterproof ability
 
Power supply waterproof and waterproof is there, but protective ability difference is very big, the rain only require IP65 protection grade, waterproof protection grade requirements
 
IP67, means that even if the power supply in the water, also can use safety, to avoid moisture moisture, salt fog and other internal PCB circuit of power supply and the influence of the components.
 
Power supply with the potting process, completely reach IP67 degree of protection, to prevent moisture or salt fog breathing effect caused by the power failure, special potting materials at the same time
 
Heat conduction performance is also very good, can help power cooling, potting process although increased the cost, but products use reliable, late can put an end to quality hidden trouble.
 
LED power supply in addition to the above three kinds of protection ability, LED power supply should also possess over temperature protection, over voltage protection, under-voltage protection, short circuit protection, and protective functions.
