Raymond,
 
It is quite simply that when the LVD was first published (32 years ago in
1973!!) voltages below 50Vac, 75Vdc were not considerd to present a hazard,
and of course there were not nearly as many low voltage powered devices around
then.
 
However, the R&TTE Directive applies the requirements of the LVD without lower
voltage limit, so anything that falls within the scope of R&TTE is covered.
 
Further, the LVD itself is currently under review, and it seems very likely
that a new LVD will also remove the lower voltage limit.
 
Of course, some standards, notably 60950, include voltage limits within their
scope, so no doubt they will also have to be revised, but applying them to low
voltage products regardless of what the scope says is simply demonstrating due
diligence in addressing product safety.

Subject: Electronic products operating below 50 Vac/75 Vdc



The scope of LVD directive includes electrical products operating 50-1000
Vac/75-1500 Vdc.  On the market, a lot of electrical products especially
electronic products are operating under 50 Vac/75 Vdc.  Why doesn't LVD
Directive cover the products operating under such voltage?  Can someone advise
which directive or regulation covers this loophole in EU currently. 

Thanks and regards, 

Raymond Li
