CLP30-200B1
7/11
This current (typically above 150 mA) should not activate the protection device CLP30-200B1.
Therefore the level of activation is to be chosen just below this limit (typically 200mA). This level is adjusted
through R
SENSE
.
Figures 7a and 7b enable the designers to choose the right R
SENSE
value.
Example:
The choice of
R
SENSE
= 3
ensures a negative triggering of -280 mA min and -380mA max.
In this case, the positive triggering will be 220mA min and 320mA max.
Thanks to the CLP30-200B1 topology, the surge current in the line is reduced after it.
Because the remaining surge energy is low, the power ratings of R

Switching-on current versus R
SENSE
The choice of the switching-on current is function of the R
SENSE
resistors.
