6 B) ]' D& c' D! p一个电子开关(继电器控制输出),它的环境温度标T45,请问测量正常温升是在环境温度20度测量吗? 请参照IEC61058-1标准中的第16.2.2条例Switches with a T-rating up to and including 55 °C are tested at an ambient temperature of
. {8 @% R& ?* u$ Y) Y8 ]) M25 °C ± 10 °C. Switches with T-rating above 55 °C are placed in a heating cabinet without # H q" i( r# \! @! M+ d1 ~ z
forced convection and the temperature is raised to the T-rating of the switch. The
