请教Class 2 transformers

gzsl2009

有谁知道Class 2 transformers的具体信息，好像就是我们平时说的安全隔离变压器吧？ 我现在不能确认了，请知道的高手指点一下。
或谁有UL 5085-3-2006 Part 3: Class 2 and Class 3 Transformers，借我看看

安全隔离变压器，如果我没有记错的话，是对的

是安全隔离变压器。

Class 2 transformers是UL标准体系中特有的一种分类, 是指输出电压,输出电流和输出功率附合Class 2类要求的变压器.

标准定义如下:
CLASS 2 TRANSFORMER – A transformer that has a 30 V rms maximum secondary potential
under any condition of loading.
Note: The impedance within an inherently-limited transformer limits the current output to a particular maximum value.
Maximum power is limited by winding impedance (inherently limited) or by overcurrent protection (not-inherently limited).
It may or may not be provided with a thermostat or other temperature sensitive device to limit its maximum temperature.
A not-inherently limited Class 2 transformer is provided with overcurrent protection to limit the maximum power output.

Class2是北美体系的一个概念，指的是电源的输出电压、输出电流和最大输出功率被限制在一定范围内的变压器。即交流输出峰值电压不超过42.4V，额定输出电压30V，直流输出不超过60V。在任何负载状态下包括短路，输出最大电流不超过8A。额定输出功率不超过100VA安全隔离变压器
