CE认证EMC指令LVD指令要测试哪些内容


    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMC全<span style="color: black;">叫作</span>Electro Magnetic Compatibility,即电磁兼容指令(2014/30/EU),<span style="color: black;">指的是</span>系统或设备在所处的电磁环境中能正常工作,<span style="color: black;">同期</span>不会对其他系统和设备<span style="color: black;">导致</span>干扰。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMC<span style="color: black;">包括</span>两部分:EMI(电磁干扰)和EMS(电磁抗扰度)。EMI(电磁干扰),是<span style="color: black;">设备</span>本身在执行应有功能的过程中所产生<span style="color: black;">有害</span>于其它系统的电磁噪声;EMS(电磁抗扰度)<span style="color: black;">指的是</span><span style="color: black;">设备</span>在执行应有功能的过程中不受<span style="color: black;">周边</span>电磁环境影响的能力。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">EMC指令<span style="color: black;">包括</span><span style="color: black;">那些</span>测试项目?</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、EMI(电磁干扰)<span style="color: black;">包含</span>:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">辐射骚扰——RE:(Radiated emission)</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">传导骚扰——CE:(Conducted emission)</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、EMS(电磁抗扰度)<span style="color: black;">包含</span>:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">辐射抗扰度——RS:(Radiated Susceptibility)</p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q3.itc.cn/q_70/images01/20240313/766e7d8f4dab473180581c19f5405aed.jpeg" style="width: 50%; margin-bottom: 20px;"></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">什么是LVD指令?</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">LVD全<span style="color: black;">叫作</span>Low Voltage Directive,即低电压指令(Low Voltage Directive 2014/35/EU)。LVD的目的<span style="color: black;">保证</span>低电压设备在<span style="color: black;">运用</span>时的安全性。LVD指令适用范围为交流在50V至1000V和直流75V至1500V之间的电器<span style="color: black;">制品</span>,LVD<span style="color: black;">包括</span>设备的所有安全规则,<span style="color: black;">包含</span>防护因机械<span style="color: black;">原由</span><span style="color: black;">导致</span>的危险。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">LVD指令<span style="color: black;">包括</span><span style="color: black;">那些</span>测试项目?</p>
