针对SELV供电含有TNV电路的路由器等,我们是定义为Class III ,还是Not classified
如题,看看大家的意见,个人觉得可以定义为class III,即SELV供电,且不会产生危险电压。TNV电路是既不满足SELV电路,也不属于危险电压电路。
1.2.8.6
HAZARDOUS VOLTAGE
voltage exceeding 42,4 V peak, or 60 V d.c., existing in a circuit that does not meet the
requirements for either a LIMITED CURRENT CIRCUIT or a TNV CIRCUIT.
赞同,,,, 我觉得写成哪种都可以,只要SELV部分和TNV部分该做的隔离做好了就行 我认为不可以定义为Class III类设备,只从定义就可以看出了:
CLASS III EQUIPMENT
equipment in which protection against electric shock relies upon supply from SELV CIRCUITS and in which HAZARDOUS VOLTAGES are not generated.
只有是SELV电路供电的才能定义为III类设备。
TNV电路又不是SELV电路,如何能混为一谈,可以定义为I类/II类。 赞同不可定义为class III
