什么是符合 IEC 60601-1-11标准的医疗电源?
IEC 60601-1-11IEC 60601-1标准的最新版本,用来保证家庭环境中使用的医用电气设备的基本安全性和基本性能。 从2013630在欧盟生效,20131231在美国生效,新标准在几个关键方面与以前的版本有所不同。 现在,它需要对医疗设备进行“ II类”电气分类,高防护等级(IP)和家庭使用系统,并将“家庭环境”的定义扩展到欧洲的疗养院。
IEC 60601-1-11医疗电源是
符合IEC 60601-1-11法规中指定标准交流直流转换器。 除了医疗电源的基本要求(如具有耐高压和低漏电流)以外,家庭医疗保健电源组还要求达到II类和最低IP21防护等级。 电源产品CBUL和其他法规报告中也注明IEC 60601-1-11
如何知道自己是否需要IEC 60601-1-11家庭医疗电源?
终端使用性质以及该设备的使用位置将决定是否有必要符合IEC 60601-1-11

符合IEC 60601-1-11是否对电源类型是否有要求
GlobTek大多数医疗电源和ACDC适配器都符合IEC 60601-1-11GlobTek提供符合标准的桌面式或插墙式电源。 交流转直流适配器满足IEC 60601-1-11的主要条件是它们属于II类且具有较高的防护等级。

什么是IEC 60601-1医疗级额定电源交流适配器?

IEC 60601-1-2医疗级额定电源交流适配器将来自墙壁的输入线路电压转换为较低的电压,通常为直流,该电压用于操作和最终使用医疗设备。 IEC 60601-1-2医疗级电源交流适配器通常装在塑料外壳中,并提供2脚和3脚输入选项。另外开放式电源医疗设备内部.这些交流转直流转换器是根据国际医学标准设计的,并确保它们符合某些方面的要求,不同于通用信息和通信技术设备的电源。

为什么医疗级IEC 60601-1电源通过了IEC 60601-13版认证,而最新标准IEC 60601-14版?

IEC 60601-1在安全和EMI / EMC规范中有区分IEC 60601-1安全部分的最新版本是第三版,而EMI / EMC的最新版本是60601-1-2,第四版。





IEC 60950-1IEC 60601-1医疗级额定电源有什么区别?

IEC 60950-1IEC 60601-1-2电源都是起到交流电转直流电的作用,可以是内或外根据应用终端的不同规格要求而设计。 尽管例如输入和输出电压以及结构等类似,但也存在许多差异。 例如一些重要区别在于,医用IEC 60601医用级交流转直流适配器能够承受较高电压,并且必须具有较低的漏电流。 根据终端应用的不同,还有许多其他差异和考虑因素。

医疗设备必须包含一种或多种保护手段(MOP),以使患者和操作员免受电击危险。 保护手段(MOP)可以是安全绝缘,保护性接地,规定的爬电距离或气隙或其他保护性阻抗。 这些可以各种组合使用。 IEC 60601-13版区分了对患者的风险和对操作人员的风险。 因此,MOP可以分类为患者保护方式(MOPP)或操作员保护方式(MOOP)。 MOOPMOPP之间的主要区别是允许的爬电距离。 使用基本绝缘可以满足这两个要求。 为了获得2倍的MOPP认证,隔离测试在4000 Vac时特别要求,8mm的爬电距离是MOPP所要求的两倍。

什么是主体触体绝缘型和心脏触体绝缘型符合IEC 60601-1-2医疗级额定电源交流适配器,有什么区别?

医用级电源和交流转直流适配器分为三种应用部件类型:主体类型(B),主体触体绝缘型(BF)和心脏触体绝缘型(CF)。这些应用的零件需要特定的属性,例如隔离电压,爬电距离和漏电流。绝缘是指未接地的II类电源,该电源未关联到另一个输出且已完全隔离。 B型是指在患者附近工作的设备,如IEC 60601-1中所述,围绕患者的椅子或床六英尺,并且不通过电子方式接触患者并且接地。这些设备包括手术室照明设备,医院推车和床,药物和补给品的自动分配器以及X射线机之类的诊断设备。 BF型设备向患者或从患者发送电能信号,例如电外科设备,内窥镜和生命体征电子监护仪(例如温度计)。 CF型设备与BF类似,不同之处在于它们为连接到心脏的设备(例如除纤颤器,外部起搏器或心内心电图电极)供电,并且CF型需要比BF型更高的电击防护等级。

根据美国能源部的规定,如果EPS使用任何类型的电气连接,电缆,软线或其他电线(包括可移动的和硬的)连接到最终用途应用,则可以被视为AEPS。 有线连接。 以太网电缆将满足这些标准,因此通过以太网电缆连接到最终用途产品的EPS仍将被视为AEPS,并且如果满足其他5条标准,则将遵守适用的节能标准。 AEPS。 通常,所有以太网供电电源适配器都符合所有标准,并且必须达到VI级效率

什么是符合IEC 62368-1:2018标准电源?
IEC 62368-12018适用于额定电压不超过600 V的音频,视频,信息和通信技术以及商用和办公领域中的电气和电子设备安全。这是产品安全标准 对能源进行分类,规定针对这些能源的防护措施,并就这些防护措施的应用和要求提供指导。 规定的防护措施旨在减少痛苦,受伤的可能性,并在发生火灾时减少财产损失。 符合IEC 62368-1交流直流转换器或电源是经过测试并证明符合所述标准的电源。

IEC 62368-1电源是否替代了IEC60950-1电源?20201220日,已应用于信息技术设备和音频视频设备的安全标准IEC 60065IEC 60950-1过渡为IEC 62368-1。 在北美,ETLUL 60950-1认证将继续有效,并且可以继续使用直至另行通知。

IEC 62368-1IEC 60950-1电源之间有什么区别?

尽管标准结构和内容总体上有很大不同,但以前符合IEC 60950-1的大多数产品经过很小的修改甚至不用修改都可以符合最新标准IEC 62368-1

IEC 60950-1电源,直至另行通知。


一到六是国际能效标记协议,允许制造商指定产品的效率性能。 此性能基于对在不同负载水平下测试的外部电源或交流转直流适配器的工作能效和空载功耗的测量。 空载功耗是指即使应用程序关闭或断开连接,外部电源也要消耗的电量。


什么是生态设计指令2009/125 / EC


什么是IEC 60335-1

国际标准60335-1涵盖了家用和类似用途电器的安全,单相电器的额定电压不超过250 V,其他电器的额定电压不超过480V

为什么必须使用符合IEC 60335-1额定电源或交流适配器?

在家庭环境中使用的设备应用必须使用经IEC 60335-1认证的电源或交流直流转换器。 这些独特的电源提供了家用电器所需的特定合规性。

What is the The Unique Device Identification (UDI) for my GlobTek medical grade power supply?

The Unique Device Identification (UDI) as required by the Food and Drug Administration Amendments Act of 2007 and EU Medical Device Regulation (MDR) is required for registered medical devices. While GlobTek medical grade power supplies carry full medical certifications they're actually not considered medical devices themselves but a component of such.
