This current (typically above 150 mA) should not
activatethe protectiondeviceCLP30-200B1.
Thereforethe levelofactivationis tobechosenjust
below this limit (typically 200mA). This level is
adjustedthroughR
SENSE
.
Figures 7a and 7b enablethe designersto choose
the rightR
SENSE
value.
example
The choice of
R
SENSE
= 3
ensures a negative
triggeringof -280 mA min and -380mAmax.
In this case, the positive triggering will be 220mA
min and 320mAmax.
Thanks to the CLP30-200B1 topology, the surge
current inthe lineis reducedafter it.
Because the remaining surge energy is low, the
power ratings of R
P
, the relay contacts and the
externalvoltagereferencedevicemay bekeptlow.
This results in a significant cost reduction for the
wholesystem.
