IEC61558-2-16 的 12.101好像有要求?
The no-load output voltage or the rated output voltage of switch mode power supply
units shall not exceed:
– 1 000 V a.c. or 1 415 V ripple-free d.c. when separating transformers or autotransformers
are used;
– 500 V a.c. or 708 V ripple-free d.c. when isolating transformers are used;
– 50 V a.c. or 120 V ripple-free d.c. when safety isolating transformers are used.
The no-load output voltage or the rated output voltage of independent switch mode
power supply units shall not be less than:
– 50 V a.c. or 120 V ripple-free d.c. when separating transformers or autotransformers are
used. 作者: 山炮 时间: 2013-5-15 20:36
关系不大:有些关系,并非完全无关。应该用"有些关系"更好。
隔离变压器和安全隔离变压器就是以电压区分,安全隔离变压器是一种低电压的隔离变压器。分离变压器与隔离变压器的根本区别是分离变压器的绕组间只是基本绝缘,而隔离变压器是加强绝缘或双重绝缘。作者: jcyxb 时间: 2013-5-15 22:08
