Three alternatives come to mind:
transformers, caps, or "no connection".
You can use a very small transformer to isolate the mains while
maintaining great ac
I'm hoping someone could clarify the EU law.
I've been told a EU member's government agency has taken one of our
products to a Competent Body to verify conformance to the Directives.
My understanding of the law is that there must have been a complaint, or
incident, from a customer, for this to oc
Item Subject: German Dioxin regulation
Hello Bharat,
On July 6th, 1994, the German Government formally revised the "Chemical
Prohibition Regulation" to include various congeners of brominated dioxins
and furans. This legislative action, referred to as the "German D

I just read a message on this group from Kevin Richardson which states:

Hello everybody. I've quite enjoyed listening to all of you "talk" for some
time (8 months), although I've been rather quiet. I look after certification
of mainly medical devices at CSA (I also do test & measurement and
laboratory equipment). I kind of regret asking this loaded question, but

Hello,
You might use clause 2.4 of IEC950 or clause or clause 6.3.1.2 of
IEC1010 depending what standard is valid for your equipment. LIMITED

transformer or optocoupler.
This enables you to measure on AC (primary) and connect
Hello.
I don't know your application here of course, but it may not meet your needs
simply to divide the incoming line voltage and give it to an ADC, since that
would connect your logic ground to the AC neutral at the ADC, and this might not
be a good plan. Using the "ground" reference fr

Why not just use a precision voltage divider, and then feed the reduced ac
voltage to your A/D. If you need only positve voltage, then couple into the
A/D with a capacitor and add a precise DC offset voltage.

Probably not the best way to do it!
