Subject: RE: EN61000-3-2 Amendments. (Document link: Robert E. Heller)
My read on this is if the equipment can be operated (in real life) with the
battery charger attached then it must be tested with the battery charger in
place (this would be worst case configuration).
If it cannot be operated then test the battery charger with the unit not
operating (charge mode only).
I do not believe that you can declare "non-compliance".
For others reading................would it be O.K. to declare in the
operator's manual that the unit must not be operated while charging?

Agreed Jim,
I just got done testing a portable piece of test equipment that has a AC
power draw of 110W nominally, this equipment has a lead acid battery that
provides battery operation, when the battery is fully charged the equipment
passes class A marginally (10% under the limit worst case), but when the
battery charger is running the AC power draw increases 20 Watts and the
13th
harmonic goes out of spec (8-10% above limit).
My question is, can we specify compliance to the specification when the
battery is suitably charged, and note non-compliance if the first condition
is not meant?

Jim: You wrote "essentially anything will pass now". Oh how I wish that
were true!
The absolute requirements do make it easier for low power equipment to
pass,
but for anything above several hundred watts all bets are off and running
the test can lead to ugly surprises. For example, I recently tested 2
battery chargers to A14: one with approx. 400W draw and the other approx.
800W. The 400W one just barely passes and the 800W one fails miserably.
Smaller bulk filter caps would help, but there's that pesky functionality
thing!

Al,
It relaxed the limits for almost all products except ITE, TV's, etc. I do
not remember all the details since I have not had to apply it yet.
Essentially the harmonic current limits are no longer relative based on the
power consumption of the device but based are on absolute values as if the
product was drawing 15A(not sure of this exact #). But essentially
anything will pass now. You can purchase A14 on the IEC web site at
www.iec.ch There is also a 75 watt exemption. Products less that 75
watts automatically comply.
Best regards,
Jim'

In a nutshell how did A14 change 61000-3-2. I don't have a copy of
A14 yet.
