关于加湿机UL998标准问题讨论
加湿机UL998标准中,42.11章与42.12章,42.11For an extra-low-voltage safety circuit, if operation of the product with a short circuit or grounded
circuit may result in unsafe operation of the controlled device, spacings shall be not less than as specified
in Table 13.
42.12For extra-low-voltage nonsafety circuits, spacings are not specified.
其中的extra-low-voltage safety circuit与extra-low-voltage nonsafety circuits怎么理解??谢谢
请教高手,能否解读一下此标准,谢谢 2003版本还是2006版本??
