UL1310的泄漏电流和其它标准要求的不同(如测量位置,测量网络), 测量位置应该有4点:& z0 b/ i, @0 @: ]
(a) between exposed conductive surfaces and the grounded pole of the supply circuit.- {: h6 I2 a( W0 t! Y/ \1 a
: r4 E6 v: B: ~! I) p" m! H" {(b) between output circuits and the grounded pole of the supply circuit.
( @' b$ A! J2 q. `
( O V( y4 D8 P3 r6 t(c) between output circuits and exposed conductive surfaces.
9 b: T* h8 b* E1 p; i
- d4 Z9 n, w1 i3 J3 R# ^(d) with output circuits conductively connected to exposed conductive surfaces, between output circuits/exposed conductive surfaces and the grounded pole of the supply circuit.; D9 O7 h- _3 W& I4 N
/ w& z2 M0 k2 S5 v0 @: _如果你的电源产品初次之间没有跨接电阻或电容, 那么测出来的值应该很小,可能就是0.05mA左右. |
