Information
Increased current on switch-on or after a test pulse from an OSSD
Due to the support capacitors of the safe shut-
down method, there is an increased current
consumption on switch-on and after a test pulse from an OSSD. The Safe Pulse Block is equipped
with an active current limiter in order to reduce the load on safety outputs to a minimum.
