大家来分析这个电源是用UL60950-1还是UL1310
今天遇到一个怪怪的问题，我们的电源去申请UL的时候，本来是申请的UL60950-1，但是UL的工程师评估够却说是使用UL1310，大家来说说用什么标准好。 先说说这个电源是用来做什么的。就是，它的用途是什么，给哪类产品来供电的？ 从你提供的照片来看可能需要UL1310+UL2089, AC供电的部分做UL1310, DC供电部分类似于车充做UL2089. 它的用途是什么? 才能定具体的测试标准? 学习，应该根据它的使用用途吧。 同意2楼说法! 首先要明确这个是干什么的。UL1310的适用范围如下：
1 Scope
1.1 These requirements cover indoor and outdoor use Class 2 power supplies and battery chargers
intended for use on alternating current branch circuits with a maximum potential of 150 V to ground. These
requirements apply to:
a) Portable and semipermanent mounted direct plug-in units provided with 15 A blade
configurations for use on nominal 120 or 240 V branch circuits;
b) Cord- and plug-connected units provided with a 15 or 20 A attachment plug configuration;
and
c) Units permanently connected to the input supply.
Units may also be provided with a direct current input jack for being powered from a vehicle battery
adapter. These units utilize an isolating transformer and may incorporate components to provide an
alternating- or direct-current output. Each output provides Class 2 power levels in accordance with the
National Electrical Code, ANSI/NFPA 70. Maximum output voltage does not exceed 42.4 V peak for
alternating current, 60 V for continuous direct current. These products are intended primarily to provide
power to low voltage, electrically operated devices.
1.2 These requirements cover products whose input power does not exceed 660 W under any possible
condition of output loading.
1.3 These requirements do not cover the effect that a power unit may have on the equipment or system
to which it is connected.
1.4 A product marked for a specific end-use (such as for use with audio-, radio-, or video-type equipment;
medical or dental equipment; or tools) may be subject to additional requirements found in the applicable
end-product standard. See 51.4.
1.5 These requirements do not cover products intended to charge batteries for starter motors used to
start engines. Products of this type are covered by the Standard for Battery Chargers for Charging
Engine-Starter Batteries, UL 1236.
1.6 These requirements cover Class 2 products, as defined in this standard, intended for use with toys.
Products of this type shall also comply with the Standard for Toy Transformers, UL 697.
1.7 These requirements do not cover products with outputs other than Class 2, nor battery chargers
intended to charge batteries employed in wheel chairs or similar types of mobility aids. Products of this
type are covered by the Standard for Power Units Other Than Class 2, UL 1012.
1.8 Products without a rectifier may be covered by the Standard for Low Voltage Transformers – Part 1:
General Requirements, UL 5085-1, and the Standard for Low Voltage Transformers – Part 3: Class 2 and
Class 3 Transformers, UL 5085-3.
1.9 These requirements do not cover products powered solely by a dc source. Products of this type are
covered by the Standard for Power Converters/Inverters and Power Converter/Inverter Systems for Land
Vehicles and Marine Craft, UL 458, or by other requirements appropriate for the intended application.
1.10 These requirements do not cover products intended for supplying low voltage landscape lighting.
Products of this type are covered by the Standard for Low Voltage Landscape Lighting Systems, UL 1838.
而GB4943，即950的适用范围：
1.1 范围
1.1.1 本标准适用的设备
本标准适用于电网电源供电的电池供电的、额定电压不超过600V 的信息技术设备.包括电气事务设备和与
之相关的设备.
本标准还适用于设计和预定直接连接到通信网络的信息技术设备.不考虑供电的方式.
本标准还适用于设计使用交流电网电源作为通信传播媒介（见第6 章注4）的信息技术设备.
本标准规定的一系列要求是为了减小操作人员和可能与设备接触的外行人员遭受着火、电击或伤害的危险.
当特殊说明时，也包括维修人员.
本标准旨在减小被安装的设备在按制造厂商所规定的方法进行安装、操作和维修时的危险.被安装的设备可
以是由若干设备单元互连而成的系统.也可以是由若干独*立的设备组成的系统.
属于本标准范围内的设备列举如下：
记帐机，簿记机，计算器，现金出纳机，复印机，数据电路终端设备，数据预处理设备，数据处理设备，
数据终端设备，听写设备，碎纸机，复制机，电动绘图机，消磁器，传真机，按键电话系统，磁带卷绕机，邮
件处理机，显微办公设备，调制解调器，货币处理现，包括自动出纳（现金分发机），削铅笔器，个人计算
机，照片打印设备，绘图仪，销售终端机（包括相关电子秤），邮资机，公共信息终端，订书机，电话应答
机，电话机（有线的和无线的），文本处理设备，打字机，直观显示装置，打印机，扫描仪，路由器，多媒体
设备，网络终端设备，无线电基站，中继器，通信交换设备等.
这里所列举的设备并未包括所有的设备，因此未列出的设备并不一定不在本标准的范围内.
符合本标准有关要求的设备就可以认为该设备能与需要信息处理的过程控制设备、自动试验设备以及类似
系统配合使用.但是，本标准不包括设备的性能或功能特性的要求.
故如果只是做电源的话，个人觉得是UL1310 我们只是做前面有插头部分的，主要是给手机或者GPS充电的。谢谢各位， 其實 這是可以做950-1的, 因為可以判斷為資訊類產品! 再者 你這產品做UL 1310 我是覺得你的結構很難過的, 因為看起來你的電路板部分很小!!!!! 这个是正是我所担心的。UL1310基本过不去。。。UL也是认为需要UL1310，，如果他们强行要求申请UL60950，那么他们的意思是要补做不少测试，费用也要比UL1310高出很多，难啊。。
