Galvanische Trennung - Sicherheitsrichtlinien

Das Datenblatt sagt auf Seite 2:
"The NKE series has been recognized by Underwriters Laboratory for 
functional insulation. Both input and output should normally be 
maintained within SELV limits i.e. less than
42.4V peak, or 60VDC. The isolation test voltage represents a measure of 
immunity to transient voltages and the part should never be used as an 
element of a safety isolation system.
The part could be expected to function correctly with several hundred 
volts offset applied continuously across the isolation barrier; but then 
the circuitry on both sides of the
barrier must be regarded as operating at an unsafe voltage and further 
isolation/insulation systems must form a barrier between these circuits 
and any user-accessible circuitry
according to safety standard requirements."

Das ist doch eindeutig.

Zur Frage. Man kann auch Netz messen, ohne isoliert zu sein. Falls der 
fliessende Strom hinreichend gering ist.
