多谢各位的回复, 那基本上输入线是要满足18AWG, 我现在LED 驱动的部分PWB上是没有变压器的,所以我可能描述的非隔离是错误, 所以应该输出线也要按照高压来评估,满足18AWG, 另外目前我们的灯具针对lamp base 的触点是直接焊上两条电线,标准要求:6.2.2 A soldered joint shall be mechanically secure before soldering 需要机械固定,2 s$ c2 i3 l6 B; b
6.2.3 A wire is considered to be mechanically secure when one or more of the following is provided:. E! m4 p3 F% O, s6 {
a) At least one full wrap around a terminal,
& J* \, x2 @& s3 E7 v" B9 f- ~b) At least one right angle bend when passed through an eyelet or opening, except on printedwiring' u6 s+ F/ b, }. u+ h, M
boards where components are properly inserted and soldered or mechanically secured
* f( q" {. E$ @$ Gby design, or" Z9 I( L8 n8 t, N* {. D
c) It is twisted with other conductors.所以我要确定是不是机械固定必须按照6.2.3的a,b,c, |
