8.2 Output circuits of SELV- or SELV equivalent control gear may have exposed terminals if
– the rated output voltage for constant voltage control gear or maximum output voltage for
constant current control gear under load does not exceed 25 V r.m.s.;
– the no-load output voltage does not exceed 33 V r.m.s. and the peak does not exceed
33 2 V.
可是分类里这样写的:
6 Classification
– SELV-equivalent or isolating controlgear (this type of controlgear can be used instead of
double-wound transformers with reinforced insulation; see IEC 60598-2-6 (to be read as
for LED modules where lamps are mentioned));
– auto-wound controlgear;
– independent SELV controlgear.
