Isolation 1kV card overview
l
The isolation between the channel and chassis is classified as
REINFORCED
. This can be seen as double isolation, which is necessary
because the chassis might be accessible (conductive parts can be touched)
to users (personal safety).
l
Isolation between channels is
BASIC
, since a channel is not accessible.
Therefore, there is no direct risk to users (product safety).
l
REINFORCED
or
DOUBLE
isolation has higher test values than
BASIC
isolation.
