I did not check in this specific standard (yet) but
normally both tests have different criteria for the EUT
passing. The earlier has a B-type criterion and
the latter (more severe has a C-type criterion.
B means: continue to work after the dip (interference during may happen)
C means: continue
Don,
I'd recommend that you use a rules-based checker rather than a simulator.
Cadence has a module, entitled EMControl which has a wide variety of rules
already built-in. Note that most of them will probably not be applicable to
your design and that you'll have to pick and choose judiciously.
Mark,
Welcome to the group. There are a few of us here who work with
combination electrical and laser systems such as yourself. I didn't see
any replies from any of the other usual suspects, so I'll jump in.
Laser safety and power supply safety are USUALLY two separate issues. Most

SCV EMC Society Meeting
Emerging standards for Europe
Tuesday, February 13, 2001
The February meeting of the Santa Clara Valley EMC Society will be held at SGI
in Mountain View, 1600 Amphitheatre Pkwy., building 40, in the Presentation
Center above the lobby.
The social gathering will start at
ETS 300 386-2 requires a performance criteria R surge of 4kv Line-Ground
for other than telecommuncations centres, ac power ports (Section
5.2.4.8). Keep in mind this standard only applies to Telecommunication
Network Equipment, so depending on what you make, this may be
irrelevant.

Hello Group,
I just received a brand new, shiny copy of EN 61000-6-2. The voltage dip /
interruption requirements are not clear to me. Table 4 quantifies dip and
interruption levels as % reduction. So, when they say a 30% reduction,
I assume they mean that the voltage is reduced to 70% of its

IEC60825 Part 1 deals solely with lasers. Inparticular the classification
limits, labeling requirements, user guide requirements and most importantly,
the safe operation procedures. I strongly recommend you read the standard before
using a Class 3A Device.
Your whole system should meet

Hello friends,
Our PCB staff is looking for layout tools to enhance EMC compliance. Any
suggestions?

Hi Mark . . .
I'll try to keep this brief, the EN 60825 Standard applies to the optical
(laser or LED)
portion of the product - AEL (Accessible Emission Level), wavelength,
interlocks (if required),
labelling, etc..
It does not address all the other 'product safety' parameters such as power
I use AC when it's required by standard. I also have used it on simple devices
such as transformers. However I have changed some large SMPS transformers back
to DC testing due to the high capacitive current load on the tester.
A number of years ago I changed the routine test from AC to DC on
Hello everyone,
I am new to laser regulation and was wondering if there is such a thing as
your basic open frame power supply meeting the requirements of IEC60825? I
need a + 15 Vdc output at approximately 100 Watts. I have not read the
standard yet and don't know how it compares with IEC60950.
I cannot answer for all the countries involved,
but I can quote the document which was delivered
to my home address in 1995 from my electricity
supplier (Scottish Hydro-Electric), and which,
naturally, I brought into work and filed under
230V harmonization : -
DECLARED NOMINAL SUPPLY VOLTAGE
...
The 240V countires agreed, but never changed their nominals, as this
would have involved serious changes to their power generation equipment.
...
Hi George and All!
The statement quoted above raises some doubts in me.
Since 1983 the nominal voltage of existing 220/380V and 240/415V
Is anyone familiar with limits to operating frequencies for ISM equipment in
Lithuania? I've checked http://www.radio.lt/frequency_table.htm
and I note several bands (6MHz) _reserved_ for use by ISM, but are there any
corresponding prohibitions for ISM operation? My induction heating equipment
Kim,
Take a look at EN60958-2-3: 1994 (LVD).For EMC I recall some discussion about
make use of the new EN 50293:2000 or the generics EN 50 081-1 / EN 50 082-2.
