备注： 1.以上参数测试条件为：230VAC输入，额定负载,25℃ 70%Rh,温度。 2．容差： 包括设定容差，线路稳定度，负载稳定度。 3．纹波测试：20MHz用“A12”双绞线，中断用0.1uF&47uF电容器短路。 4．进线电压稳定度测试：满负载时进线最低电压到最高电压。 5．负载稳定度测试：负载从0%到100%。 6.C3、4、32必须拆除。 Note : 1. The testing condition for the parameter above is : 230VAC input ,rated load, 25℃ 70%Rh. Temperature. 2. Error, include the setting error, line stability and load stability . 3. Wave test: adopt “A12” double wire for 20MHz, and 0.1UF & 47UF capacitor short-circuit for interrupting. 4. Inlet voltage stability test: when is over load, the lowest voltage of inlet is up to the highest voltage. 5. Load stability test: The load is from 0% to100% 6.C3、4、32 must be knocked down. | ||||||||
