关于PTC加热元件的测试
现有一产品是采用PTC元件加热的,在测试的时候其功率是一直在跳变减少的,那我想请教一下各位大侠,我在测试输入和温升的时候应该怎么样测试和记录数据呢?!请各位帮忙解答一下,谢谢!取一个阶段的平均值! IEC 60335-2-23:2012中10.1, 10.2:The representative period for appliances incorporating PTC heating elements is 30min.; 地瓜 发表于 2013-9-4 16:38 static/image/common/back.gif

哦哦,这样子的啊,谢谢! Section 36 of UL859: Exception: The power input of an appliance that uses a positive temperature coefficient (PTC) heating.
element shall be measured 1 minute after it has become energized
带PTC元件的器具,在标准规定0.85倍额定功率时,输入电压是多少呢? 有无温控,有不同 lbqwxf3706 发表于 2013-9-4 19:18 static/image/common/back.gif
