当电流大于16A时,谐波与闪烁需要满足哪个标准呢?
普通常见的谐波与闪烁标准下面两个标准是适用小于等于16A的产品
EN 61000-3-2 Harmonic current emissions
EN 61000-3-3 Voltage changes, voltage fluctuations and flicker
下面两个是比较少见的,电流大于16A的产品,适用如下标准
[*]EN 61000-3-12 Harmonic current emissions
Electromagnetic compatibility (EMC) - Part 3-12: Limits - Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16 A and ≤ 75 A per phase
[*]EN 61000-3-11 Voltage changes, voltage fluctuations and flicker
Electromagnetic compatibility (EMC) - Part 3-11: Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems - Equipment with rated current ≤ 75 A and subject to conditional connection
那么LVD指令呢?大于16A的时候还适用普通的LVD协调标准指令吗?
低压指令(LVD) (2014/35/EU)
LVD 涵盖在输入或输出电压为
[*]50 - 1000 V,用于交流电
[*]75 - 1500 V,用于直流
还有一个GPSD指令(2001/95/EC) 涵盖交流电电压低于 50 V 或直流电低于 75 V 的消费品。
所以,LVD覆盖适用范围,并没有提出电流大小,但是对电压提出的明确范围。
