I also heard the future incarnation of the LVD will start at
0V........................

Mr. Nute, 
In regards to your suggestions below, would it not be wise to take into
consideration the future plans of the LVD?  My understanding is that the LVD
will soon be called the EPSD.  Part of this change will encompass what is
referred as  "No Risk" / "Low Risk" equipment.  Would it be safe to say that
the current definition of equipment designed for use with a voltage rating
of 50-1000 V ac will change to equipment for use with a voltage rating of
0-1000V ac?

the opinions of this group are always appreciated,

Hi David:

The LVD applies to products with voltage ratings
between 50 and 1000 V ac and between 75 and 1500
V dc.

SELV does not exceed 30 V ac and 60 V dc.

Therefore, the LVD does not apply to a product
that operates from a SELV source of supply.  (We 
may be able to say that the LVD does not apply 
to a Class III product.)

However, it is appropriate to indicate in the DoC
that the LVD does not apply to the product because
the product voltage is below the lower limits of
the LVD.  

HOWEVER... EN 60950 applies to products powered
>from a SELV source of supply.  The electric shock
requirements do not apply to such products, but
the other EN 60950 requirements do apply to such
products.  These other requirements include the 
so-called "energy hazard" requirements, mechanical 
requirements, and fire requirements.

So, the product does indeed require safety testing,
but not with respect to the LVD.  The DoC should 
indicate compliance with EN 60950.  

Pragmatically, since you must test for compliance 
to EN 60950 for these other requirements, it is 
just as easy to indicate compliance to the LVD via 
EN 60950 and thereby avoid any future argument 
whether the LVD applies or not.

Most of our inkjet printer products are powered
by an external SELV source of supply.  We test
to EN 60950 and declare compliance with the LVD.


Best regards,
Rich
