输出电压230V的变压器可以符合IEC61558么?

如题,有一个变压器输出电压230V的,不知道是否可以去做IEC61558的认证。请高手指点一下。

应该施是可以的, IEC 61558-1 SCOPE 1 a)

• for isolating transformers:
– rated output for single phase transformers, not exceeding 25 kVA, and for polyphase transformers not exceeding 40 kVA.
– no-load output voltage and the rated output voltage exceeding 50 V a.c., and not exceeding 500 V a.c, or 1 000 V a.c. to be in accordance with the National Wiring Rules or for a special application.

谢谢了,之前一直局限在安全隔离变压器中了。^_^
