How are lightning protection levels specified for LED drivers?

- May 28, 2019-

IEC 61000-4-5 establishes a common reference for evaluating the immunity of electrical and

electronic equipment when subjected to surges. The test method documented in this part of IEC

61000 describes a consistent method to assess the immunity of an equipment or system against a

defined phenomenon.Surge test standards for lightning protection as below, IEC61000-4-5 ranks:

Level Open-circuit test voltage

1 0.5 kV

2 1.0 kV

3 2.0 kV

4 4.0 kV

X Special

NOTE X can be any level, above, below or in between the other levels. This level can be specified in the product standard.
