Hello all,
I'd like to hear about your experiences, including successes and failures,
if you have endeavored to gain SACI and CCEE marks for China on your own.
That is, without the assistance of 3rd parties, on your side, or the other
side, of the World. Please indicate the type of product you

Did I miss something along the way? Did Germany delete the Equipment Safety
Law of 24 June 1968 and ammended 13th August 1980? Article 3 of the law
says, The manufacturer or importer of technical equipment may only display

Dave, Mr Jensen,
Dave, your remark about gas discharge tubes would certainly lead to problems
in AC mains supplied systems, as upon ignition of the gas, at least a full
AC half period will discharge to ground, triggering any diff. mode switches

No other requirements are necessary for your products then manufacturers

The best way to design a filter is to establish the performance criteria
first.
Determine the source impedance
Determine the load impedance
Determine the attenuation required and at what frequency
Determine the roll-off required
Now you can determine what order filter you need and whether it is
Can anyone clarify please what the Czech EMC and LVD compliance
requirements are.
Is the CE mark recognised as per European countries (supported with a
declaration of conformity)?
Or is further documentation required?

Mr. Jenson,
The MOV solution will take care of the line-line surge, but don't forget
the common mode component of this test. This is usually much more
difficult to handle. You are not allowed to use MOVs from line to
ground because of leakage (at least in AC systems). The biggest problem
is
Hello Mr jensen
Just add a MOV between the phases. A 20 mm disc type will survive both
type testing
and real life surges. The smaller ones risc failure in testing if that is
done according to
the proposed test schedules (due to the limited number of pulses they can
absorb).
50% reduction of
Dear groupe,
Does anyone have some good idears about designing a simple filter for
surges (the kind of surges that comes from testing according to IEC
61000-4-5)
I was thinking about using an inductor, a capacitor and a MOV. But, what
is the requirements for the inductor ? and will it
Dear collegue,
In our EMC facilities located at the Fiat Research Center
we run Logimetrics amplifier 250 watt @ 18GHz.
They work pretty well.
