Fast increasing currents (higher than the specified I
p,max
), e.g. in case
of a short circuit, can be transmitted because the currents are
transformed directly and be limited by diodes only.
The offset ripple can be reduced by an external low pass. Simplest solution is a passive low pass filter of 1st order with
In this case the response time is enlarged.
