试回答您的问题:
1.汽车上用的东西会有特别的考虑,这在标准里的scope有说明:
NOTE 2 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
所以您在做之前跟客户确认一下.
2.这点倒是可以解决,根据25.2,超过18kg的stationary appliances可以有两种以上的供电方式,只要两种供电方式的初级电路之间满足基本绝缘就可以了.测试是打高压1250Vac,不击穿.
