Group,
We are looking at a power supply to use in a product which will have two
derivatives, one for professional broadcast use (tested to EN60950 for Europe
and UL1419 in the US.) and one for Domestic use (EN60065 and UL6500).
Traditionally we have used power supplies approved to EN60950 and UL1950, and
this has satisfied UL and our European test house.
The problem is that the power supply we intend to use for this particular
product is approved to EN60601-1 and UL2601-1 which is a medical electrical
equipment standard. I would guess that amongst other things, the creepage,
clearance would be greater and the earth leakage smaller than that of an
equivalent 60950 approved PSU?
Is there anyone who is conversant with these standards who may be able to give
me a brief summary of the main differences (relating to PSU's) between the 950
and 65 based standards and the medical standards listed above?
Has anyone ever used a medical power supply in an IT or domestic application? If
so were there any pitfalls or problems regarding the different standard
requirements? Were UL happy with its application?
Any information or advice would be greatly recieved.
Many thanks in advance.
Duncan Hobbs.
