Level  Open-circuit test voltage

1  0.5kV
2  1.0kV
3  2.0kV
4  4.0kV
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.

The lightning protection level of uPowerTek’s LED driver products is 4K/6K in common mode, and 10K in difference mode.
