我仔细的看了一下,datasheet上提到的是CSA的要求。
CSA也这么要求,看来又多了一家。
LED这东西本身就比较脆弱(3.4V左右电压),现在还要求这么高,难做啊。
看来UL 1993中有段话还是稍微人性点:
D.1.5 A device employing a solid-state component that is not relied upon to reduce a risk of electric shock
and that can be damaged by the dielectric potential may be tested before the component is electrically
connected provided that a random sampling of each day’s production is tested at the potential specified
in Table D.1. The circuitry may be rearranged for the purpose of the test to reduce the likelihood of
solid-state component damage while retaining representative dielectric stress of the circuit.
