I hope you'll all be patient with what might be a question with an
obvious answer: why do so many battery operated equipments
state that they must not be operated using rechargeable batteries?
I appreciate that NiCads have a nominal voltage of 1.2V compared
to Alkaline and Zinc Chloride's 1.5V
Courtland,
UL 1950 (and IEC 60950) clearly define their scope as "mains or battery
powered" equipment up to 600V. Your 5Vdc input device does not fall within
this scope, unless it also operates on batteries.
The standards define a Class III device, operating at similar low dc voltages.
However,
Hello group,
I have a question considering product safety for IT equipment. If a device
uses an external power supply that supplies +5V DC and has all the approvals
(UL, CE), is there any need to have the device tested to UL 1950? Can the
device be legally sold without the testing. If not, can so

Hello Terry:
D3 Deviations do not expire this year. 2nd Edition is dead...that is
correct. Specific D3 deviations, like anything else in the standard, may be
added, deleted, or changed with ammendments or editions to the UL 1950/CSA
22.2 No. 950, but in general D3 deviations are not going away.
Hi again:
In the course of a design review the option of invoking a D3 deviation came up.
Since we usually ship to the EU I have never allowed D3 deviations.
The question came to mind that I thought the D3 deviations expired this year.
Is this a foggy memory from UL 1950 2nd edition 1993 Suppl
Hello all:
We are reviewing the probability of purchasing a surge generator to do in house
compliance testing to the EN 61000-4-5 standard plus up to 6KV for some
customer specific requirements.
We have quotes from most of the major players and the equipment ranges from
very basic cost effect
Thomas,
You need consulting from a renowned laser specialist. I recommend you
contact my colleague at TUV Rheinland of North America Woody Strzelecki at
TUV Rheinland of North America; he will guide you to exactly what is
required. His e-mail is wstrzele...@us.tuv.com.
One note I have to mention
