不知道LZ从哪里看到的这个条款?7 B$ f. ^( l' \
EN 60335-1:2002 27.59 q! K% c$ O1 D7 n, Y h
A current derived from a source having a no-load voltage not exceeding 12 V (a.c. or d.c.) and

The voltage drop between the earthing terminal of the appliance or the earthing contact of the

+ y# f" O* ?; A+ M3 z: k$ @标准只是说从空载电压不超过12V的电源取得电流,电流值等于1.5倍的额定电流或者25A(取较大值).
% |5 O+ I N. T, P测试时施加的是电流,读到是是电压.通过计算能得到电阻..并不是同时施加电压和电流. |
